Why is the C-H bond length and strength different for ethyne, ethene and ethane?

Chemistry

Answer: The energy associated with a chemical bond formation determines the bond strength and its proportion/degree determines its bond length.

Explanation:

When the bond energy is higher, the 'stronger' we say the bond is between the two atoms become, and the distance between its atoms (bond length) is smaller.

Answer:

The length and strength of the C-H bond are different for ethine, ethylene and ethane due to the difference between the s characters (sp 3, sp 2, sp) in each chemical structure, which gives stronger bonds. For example, the length of the C-H bond in ethino is 1.06Å, which is also less than in ethane (1.09Å) or ethylene (1.08Å).

Like several other bonds, carbon-oxygen bonds have lengths and strengths that depend on the bond order. Draw Lewis structures fo
aniked [119]

The order of increasing C-OC−O bond length is:

                 a < c < b < e < d

                  a < c < b < e < d

Therefore, the order of increasing bond strength is:

       d < e < b < c < a

        d<  e < b < c  < a

<h3>What is bond length?</h3>

The distance between the centers of two atoms that are covalently connected is known as the bond length. The number of bound electrons determines the bond's length (the bond order). The greater the attraction between the two atoms and the shorter the bond length are, the higher the bond order.

The average distance between the nuclei of two bound atoms in a molecule is referred to as bond length or bond distance in molecular geometry. It is a transferrable characteristic of a bond between atoms of fixed kinds that is comparatively independent from the other components of the molecule.

Bond length and bond order are related; the shorter the bond is when more electrons are involved in its production.

What is the next atomic orbital in the series below? 1s, 2s, 2p, 3s, 3p, ___
Angelina_Jolie [31]
D.4s       this would be the answer because after eight electrons are added to the third orbital two have to be added to the fourth before more can be added to the third one. The third orbital can hold 18 electrons, but it first has to have eight, then two on the fourth orbital, then the rest of the ten can be added
