CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313626 Which of the following compounds would show evidence of the strongest hydrogen bonding?

1 Propan-1-ol

2 Propan-2- ol

3 Propan-1,2-diol

4 Propan-1,2,3- triol

Explanation:

More number of $H$ -bonds are possible in glycerol.

CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313627 Strongest hydrogen bond is present in

1

{CH}_{3} OH

2

{CHCl}_{3}

3

{({CH}_{3})}_{2} CHOH

4

{({CH}_{3})}_{3} COH

Explanation:

Due to $+ I$ effect, an electron-releasing group increases electron density on oxygen tending to decrease the polarity of $O - H$ bond. This decreases the hydrogen bond strength.

CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313628 The typical range of molar enthalpies for the strongest intermolecular (hydrogen) bond is

1

200 - 300 kJ

2

300 - 500 kJ

3

4 - 25 kJ

4

4 - 25 J

Explanation:

The typical range of molar enthalpies for the strongest intermolecular (hydrogen) bond is $4 - 25 kJ$

CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313629 The types of bonds present in $C u S O_{4} .5 H_{2} O$ are

1 Electrovalent, covalent and H bonds.

2 Electrovalent and coordinate bonds.

3 Electrovalent, covalent, coordinate covalent and H bonds.
