Question

The bond length decreases from C-C single bond to carbon carbon triple bond due to..

Answer 1

Explanation:

Bonds formed are more as we go fron single bond to triple

Answer 2

The bond length decreases from C-C single bond to carbon carbon triple bond due to decrease in s character.

BOND LENGTH:

• Alkanes are saturated hydrocarbons where as alkenes and alkynes are unsaturated because the presence of multiple bonds in it.
• Generally,bond length decreases with increase in bond order.
• Also bond strength is inversley proportional to bond length.
• The bond length decreases from single bond to triple bond because of the increase in s character.
• Triple bonded carbons are sp hybridized which have fifty percentage s character.
