प्रश्न
Give reasons : n-Butyl bromide has higher boiling point than t-butyl bromide.
Advertisements
उत्तर
The boiling point of n-butyl bromide is higher than that of t-butyl bromide because n-butyl bromide is a straight chain molecule having larger surface area and therefore, has stronger intermolecular forces. On the other hand, t-butyl bromide is branched molecule, so it has a smaller surface area. Hence, it has weaker intermolecular force.
