Answer: Option (c) is the correct answer.
Explanation:
A binary mixture is defined as the mixture which contains two components in the aqueous medium. The two components are solute and solvent.
And, volatility is defined as the ability of a liquid solution or substance to readily change into vapors.
For a binary solution the expression for relative volatility is as follows.
= 
where,
= relative volatility of more volatile component i
= vapor-liquid equilibrium concentration of component i in the vapor phase
= vapor-liquid equilibrium concentration of component i in the liquid phase
= vapor-liquid equilibrium concentration of component j in the vapor phase
= vapor-liquid equilibrium concentration of component j in the liquid phase
So, when
> 1 then separation by distillation is easier in nature.
Thus, we can conclude that in order to separate the components of a binary mixture, the relative volatility should be greater than unity.

Answer:
d. carboxyl
Explanation:
The presence of carbonyl group (>C=O)) and a hydroxyl group ( (−OH) on the same carbon atom is called a "carboxyl" group. A carboxyl group is represented as COOH and acts as the functional group part of carboxylic acids.
For example:
- Formic acid or Methanoic acid (H-COOH)
- Butanoic acid (C3H7-COOH)
Hence, the correct option is "d. carboxyl ".
Answer:
(b) 1 equivalent
Step-by-step explanation:
Concentration is the relative amount of a substance in a given volume or mass of something else.
An equivalent is not a concentration, because it is just a mass —the mass of a substance needed to react with or supply one gram of hydrogen.
(a) is <em>wrong</em>. 1 M means that there is 1 mol of a substance in 1 L of solution.
(c) is <em>wrong</em>. 1 % by mass that there is 1 g of a substance in 100 g of the mixture.
(d) is <em>wrong</em>. 1 m means that there is 1 mol of a substance in 1 kg of solvent.
