The C—H bond distance is the longest in

Bond length decreases with increase in bond multiplicity 2 4 2 C H Br has single bond between C-H hence bond length increases. 15. Which of the following is a correct representation of condensed formula for HOCH2CH2CH2CH(CH3)CH(CH3)CH3? (a) HO(CH2)2CHCH3CH(CH3)2 (b) HO(CH2)3CH(CH3)CH(CH3)2 (c) HOCH2CHCH3CH(CH3)2 (d) HOCH2CH2CHCH3CH(CH3)2 HOCH2CH2CH2CH(CH3)CH(CH3)CH3 is HO(CH2)3CH(CH3)CH(CH3)2.
