Question

a) Why is carbon tetravalent?

b) Why is the melting point of C4H8

lower than C5H10?​

Answer 1

Explanation:

A.The carbon atom has four electrons in its outermost shell. The word tetravalent means having a valence of four because of the prefix – tetra. ... Carbon is considered tetravalent because it has four electrons in its outermost orbital

B.Answer. Melting and boiling points of C5H10 Higher than that of C4H8 because C5H10 has more molecular mass than C4H8, so if molecular mass is more, more will be the vander wall force due to which force of attraction between molecules in C5H10 is more than C4H8.

Answer 2

Answer:

(a) The carbon atom has four electrons in its outermost shell. Carbon atoms can achieve the inert gas electron arrangement only by sharing of electrons, so carbon always forms covalent bonds.The valency of carbon is four because one carbon atom requires 4 electrons to achieve the nearest inert gas configuration. Thus, we can say that carbon is tetravalent. The word tetravalent means having a valence of four because of the prefix – tetra. Carbon is considered tetravalent because it has four electrons in its outermost orbital.

(b) Melting and boiling points of C5H10 Higher than that of C4H8 because C5H10 has more molecular mass than C4H8, so if molecular mass is more, more will be the vander wall force due to which force of attraction between molecules in C5H10 is more than C4H8.
