Description : (a) What effect the branching of an alkane has on its melting point? (L-III) (b) Which of the following has highest boiling point?(L-III) (1) 2-methyl pentane. (2) 2, 3-diethyl butane. (3) 2, 2- dimethyl butane.
Last Answer : Ans.(a) In general conception, as the branching increases packing of the molecules in the crystals becomes less close and have melting point decreases accordingly. (b) As the branching increases, ... attraction decreases and hence the boiling point decreases. So, 2-methyl pentane has highest B.pt.

Description : Why does the temperature of a substance remain constant during its melting point or boiling point? -Maths 9th
Last Answer : The extra heat supplied to the boiling water is used in the vaporization of a liquid, which is known as the latent heat of vaporization. That's why the temperature of a substance remains constant during its melting or boiling.
Last Answer : The temperature of a substance remains constant during melting and boiling points till the completion of melting and boiling. It is because substance makes use of latent heat of fusion ... between particles of liquid to change into vapours during boiling. Therefore, temperature remains constant.
