Would gas except the hydrides of N, O and F to have lower boiling point than the hydrides of their subsequent group members ? Give reasons.

a. Would you except the hydrides of N,O and F to have lower boiling points than the hydrides of their subsequent group members? Give reason. b. Can phosphorous with outer electronic configuration 3s^(2)3p^(3) form PH_(5) ? c. How many hydrogen-bonded water molecules(s) are associated with CuSO_(4).5H_(2)O ?

Why does PH_(3) have lower boiling point than NH_(3) ?

Give correct order of boiling point of hydride of group 17.

The boiling points of hydrides of group 16 are in the order

Carboxylic acids have higher boiling points than those of ethers .Give reason.
