Which is the most stable radical
triphenylmethyl radicalQuiz time: one of the most stable free radicals known is the triphenylmethyl radical, discovered by Moses Gomberg in 1900.
In the absence of oxygen, this radical is indefinitely stable at room temperature..
Which is the most stable structure
The most stable structure is one that has the fewest number of, and smallest magnitude of, formal charges and with the negative formal charges on the more electronegative atoms.
What is the weakest 3d shape
The Triangle is one of the most solid geometrical shapes. But it points out also the weakest areas in hitting, locking, stances, moving and so on.
What is the strongest Arch
St. Louis Gateway ArchThe catenary arch is regarded as the strongest arch in supporting itself. The St. Louis Gateway Arch is a catenary arch, according to Great Buildings. Built in the 1960s at 630 feet both in width and at its base, it has been standing for more than 50 years, as of 2011.
Which is the strongest triangle
equilateral triangleAn equilateral triangle is structurally the most sound for obvious reasons. Equal angles and vectors naturally resist gravitational and lateral forces equally in all directions.
Are circles stronger than triangles
The circle ie the strongest shape because it maintains constantly pressure , There is no inherent leverage as all points are at a constant distance from each other. It depends on the stress applied: downward, it’s the triangle – torsional,it’s the circle.
What is the strongest bridge in the world
The Rolling BridgeThe Rolling Bridge in London opened in 2004 is a truss bridge and is considered the strongest bridge in the world.
What is the most balanced shape
Triangles are the strongest shape.
Are triangles or hexagons stronger
For hexagonal close-packed it gets considerably more complex but triangles can still be involved. “Triangles” just in general are not the strongest shape. If you have a solid block of wood shaped like a triangle, versus a solid block of wood shaped like a pentagon, they’ll hold the same weight and what-not.
Which resonance is most stable
Rules for estimating stability of resonance structuresThe greater the number of covalent bonds, the greater the stability since more atoms will have complete octets.The structure with the least number of formal charges is more stable.The structure with the least separation of formal charge is more stable.More items…
Which is the most stable carbocation
t-alkyl carbocationThe most stable carbocation is t-alkyl carbocation because the order of stability of alkyl carbocation is t-alkyl >s-alkyl> p-alkyl *> CH3 carbocation.
What is the most efficient shape in nature
Hexagons are the most scientifically efficient packing shape, as bee honeycomb proves.
Are squares better than circles
A circle gives you more enclosed space (area) for a given distance (perimeter/circumference) than a square does, so in this case a circle is more efficient. … So squares pack together with no gaps, but circles leave gaps when packing together, so in this sense a square is more efficient than a circle.
Why are triangles stronger than shapes
They are according to the buzz on the Internet (and most stable too), despite competition from circles. Mythbusters even proclaim that “triangles are the strongest shape because any added force is evenly spread through all three sides”.
What is the strongest geometric shape and why
TrianglesTriangles: The Strongest Shape. One shape is a favorite among architects, the triangle. The triangle is the strongest shape, capable of holding its shape, having a strong base, and providing immense support.
Are hexagons the best shape
A hexagon is the shape that best fills a plane with equal size units and leaves no wasted space. Hexagonal packing also minimizes the perimeter for a given area because of its 120-degree angles.
Which paper shape is the strongest
We tried the experiment twice and both times found the circular column to be the strongest. This is because it doesn’t have any edges so the weight of the books is shared evenly by the circle. The square and triangle support the books on their edges and corners meaning they collapse.
What is the strongest angle
45 degrees is the strongest brace angle for a right-angle triangle, but the absolutely strongest is an equilateral triangle with three 60 degree angles.
What is the weakest geometric shape
TriangleThe Triangle is a solid shape. The weakest areas include hitting, locking, stances, moving and so on.
Is an arch or triangle stronger
triangular support structure for a bridge, then the arc can bear a greater load than a single triangle. … Triangles can be used to make a structure as strong as an arc, however on a one-to-one comparison, a single arced structure will be able to support more load than a simple triangular structure.
Is a hexagon stronger than a circle
A hexagon shape works well as internal trussing structure in sandwich structured composites. As a vessel it is stronger than a rectangular box of similar volume because the wall spans are shorter, but it will not be as strong as a circle for a given wall thickness.
