Which statement is correct?
(1) m. p. of \( \mathrm{H}_{2} \mathrm{O}, \mathrm{NH}_{3}, \mathrm{HF} \) are maximum in their
\( \mathrm{P} \)
respective group due to intermolecular
W
\( \mathrm{H} \)-bonding
(2) b.p. of \( \mathrm{CH}_{4} \) out of \( \mathrm{CH}_{4}, \mathrm{SiH}_{4}, \mathrm{GeH}_{4} \) and \( \mathrm{SnH}_{4} \) is least due to weak intermolecular force of attraction
(3) formic acid forms dimer by \( \mathrm{H} \)-bonding
(4) all are correct
