Question

Boiling point increases in order $C{H}_4$ < $S{H}_4$ < $Ge{H}_4$ because :

• A. atomic number of central metal atom increases
• B. molecular mass increases
• C. dipole - dipole interaction increases
• D. bond length increases

Answer 1

Answer: (B)

molecular mass increases

Boiling point increases in order $C{H}_4<S{H}_4<Ge{H}_4$
molecular mass increases. The atomic mass increases in the order $C<S<Ge$. Hence, the molecular mass increases in the same order.
