Alcohols are soluble in water. This is due to the hydroxyl group in the alcohol which is able to form hydrogen bonds with water molecules. Alcohols with a smaller hydrocarbon chain are very soluble. As the length of the hydrocarbon chain increases, the solubility in water decreases.

The chemical bond formed between amino acids, constituting the primary linkagein all protein structures. In a peptide bond, the carboxyl group (COOH) of one amino acid bonds with the amino group (NH2) of another, forming the sequence CONH and releasing water (H2O).

A chemical equilibrium is dynamic in nature which in other words means that reactions continue to occur in both forward as well as backward direction with the same speed. As a result, the amount of product formed immediately reacts backward to give reactants and so there is no change in concentration of reactant or product with the passage of time.

Ecell = E right - E left

= E•Cu²⁺/Cu - E•Zn²⁺/Zn

= (+0.34v) - (-0.76v)

=0.34+0.76

=1.1v

Correct option is A)

If rate is given by: rate =k[A]x[B]y

then the order =x+y.

This order can be a positive, negative no., zero or even fractional. It can be determined only experimentally and does not depend on stoichiometric coefficients of reactants.

The chemical formula for methane is CH4 and its molecular mass is calculated as the sum of Mass of the carbon atom and Mass of hydrogen atoms. The molar mass of carbon is 12g/mol and the mass of hydrogen atom is 1g. Therefore, the Molar mass of methane is:

12+4×1=16g/mol

As we know, 10 gram of methane on combustion gives 560 KJ of heat. So 1 gram of methane on combustion gives = 560/10KJ of heat.

Hence, 16 gram of methane on combustion give=560/10×16=896KJ

Thus the heat of combustion of methane is -896KJ/mol. Therefore, the negative sign in the answer.

The electronegativity values for the representative elements decreses down a group because of the increase in atomic radius as well as screening effect. Thus, carbon has highest electronegativity in a group.

A Ziegler–Natta catalyst, named after Karl Ziegler and Giulio Natta, is a catalyst used in the synthesis of polymers of 1-alkenes (alpha-olefins).
