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 (CH4) — London dispersion forces

Dimethyl ether (CH3OCH3) — dipole-dipole attractions

Methanol (CH3OH) — hydrogen bonding

Therefore, Methanol - CH3OH with H-Bonding have highest Boiling Point among the given chemical compounds.

Q:

India changed over to the decimal system of coinage in

A) 1947 April B) 1957 April
C) 1956 April D) 1949 April
 
Answer & Explanation Answer: B) 1957 April

Explanation:

India switched from the rupee, pie system to decimal currency on 1 April 1957. The decimalisation of currencies is the process of converting each country's currency from its previous non-decimal denominations to a decimal system, with one basic unit of currency and one or more sub-units, such that the number of sub-units in one basic unit is a power of 10, most commonly 100).


In India, Pakistan, and other places where a system of 1 rupee = 16 annas = 64 paise = 192 pies was used, the decimalisation process defines 1 naya paisa = ​1⁄100 rupee.
