Which of the following has presence of intramolecular hudrogen bonding ?

Options

A. chloral
B. `CuSO_(4).5H_(2)O`
C. p-nitrophenol
D. both (1) and (2)

Answer

B

Explanation

(1) The structure of Chloral is `C Cl_(3) - overset(O)overset(||)(C ) - H` which can not do intramolecular H- bonding.
(2) `CuSO_(4).5H_(2)O` exist as `[Cu(H_(2)O)_(4)] SO_(4).H_(2)O` which can do intramolecular H-bonding
(3) The structure of p-nitrophenol is which can do intramoleulat H-bonding.
