Question

The correct order of boiling point for isomeric primary $\left(1^{\circ}\right),$ secondary $\left(2^{\circ}\right)$ and tertiary $\left(3^{\circ}\right)$ alcohols is:

• A. $1^{0}>2^{\circ}>3^{\circ}$
• B. $3^{\circ}>2^{\circ}>1^{\circ}$
• C. $2^{\circ}>1^{\circ}>3^{\circ}$
• D. $2^{\circ}>3^{\circ}>1^{\circ}$

Answer 1

Answer: (A)

Boiling point is a property which depends upon the interaction of a particle with other particle. $1^{\circ}$ molecule was greater surface area to interact than the $3^{\circ}$ molecule.
