Bond length decrease with increase in bond-order. Hence, triple bonded carbon has minimum bond length. C-C bond-length =1.54 overset texto mathop textA C=C bond-length =1.33 overset texto mathop textA C≡ C bond-length =1.20 overset texto mathop textA

Q. Shortest $C - C$ bond length is present in:

$C H_{3} - C H_{2} - C H_{3}$

$C H_{3} C H_{2} C H_{2} C H_{3}$

$C H_{2} = C H - C H = C H_{2}$

$C H \equiv C - C \equiv C H$

Bond length decrease with increase in bond-order. Hence, triple bonded carbon has minimum bond length. $C - C$ bond-length $= 1.54 A o$ $C = C$ bond-length $= 1.33 A o$ $C \equiv C$ bond-length $= 1.20 A o$

Q. Shortest C−C bond length is present in:

CH3​−CH2​−CH3​

CH3​CH2​CH2​CH3​

CH2​=CH−CH=CH2​
