Q:

Which of the following chemical compounds has the highest boiling point?

A) Dimethyl ether (CH3OCH3)	B) Methanol (CH3OH)
C) Methane (CH4)	D) None

Answer & Explanation Answer: B) Methanol (CH3OH)

Explanation:

Chemical Compounds with stronger intermolecular forces have higher boiling points.

The order of strengths of intermolecular forces is:

London dispersion < dipole-dipole < H-bonding

${Methane (CH}_{4)}$ — London dispersion forces

${Dimethyl ether (CH}_{3} {OCH}_{3)}$ — dipole-dipole attractions

${Methanol (CH}_{3} OH)$ — hydrogen bonding

Therefore, ${Methanol -}$ ${CH}_{3} OH$ $with H-Bonding have highest Boiling Point among the given chemical compounds.$

Q:

A woman fills a bucket in 6 minutes. 1845 buckets have to be filled from 8 am. to 9:30 am. How many woman employees should be employed for this task?

A) 111	B) 117
C) 123	D) 139

Answer & Explanation Answer: C) 123

Explanation:

We know that, $\frac{M 1 \times D 1}{W 1} = \frac{M 2 \times D 2}{W 2}$

Here M1 = 1, D1 = 6 min, W1 = 1 and M2 = M, D2 = 90 min, W2 = 1845

$\frac{1 \times 6}{1} = \frac{M \times 90}{1845}$

=> M = 123
