Question

Count correct statements: (i) methanol self-associates by O–H···O; (ii) dimethyl ether boils above ethanol; (iii) n-hexane boils above n-pentane; (iv) internal H bonding can reduce external association; (v) every permanent-dipole molecule H-bonds to itself. Use conventional N/O/F–H bonding.

Answer:

3

Solution:

i, iii, iv are true. Ether lacks an OH donor and boils below ethanol. A permanent dipole does not itself supply the donor required by v. Count 3.
