List properties of water that stem from H-bonding
(b) Two two molecules indicated below are capable of forming interamolecular H-bonding Which is likely to form more stable H-bonds Give reasons
(i) `CH_(3) COCH=overset(CH_(3))overset(|)C-OH`
(ii) `CH_(3) COCH_(2)overset(CH_(3))overset(|)C-OH` .

Explanation

(i) High melting point
(ii) High boiling point
(iii ) High heat of vapourisation
(iv) Low density of ice compared to water
(v) High specific heat
(vi) High ionic conductance of `H_(3)O^(o+)` ion and `overset(Θ)OH` ions and many others
(b) The molecule in (i) has two resonance structures, which make the H-bonding more stable
The molecule (ii) has no such resonance stabilization
