Question

Which statements about substance X are correct?

i. It is a covalent compound.

ii. It has a giant molecular structure.

iii. It has the same structure as graphite.

iv. It has the same structure as diamond.

(a) I and III (b) II and III

(c) II and IV (d) I, II and IV​

Answer 1

Answer:

Explanation: 1) It is a covalent compound, 2) It has a gaint molecular structure, 3) It has the same structure as diamond , so the correct answer is d) 1, 2 & 4

Answer 2

Answer:

(d) I, II and IV​

Explanation:

• When two or more nonmetals combine, covalent bonds are created. For instance, water is created when two nonmetals, hydrogen and oxygen, combine through the formation of covalent bonds.

• The melting and boiling points of giant covalent lattices are extremely high. The entire structure of these compounds is connected by a sizable number of covalent bonds.

• Thus, in contrast to the same element crystallising in the octahedral or tetrahedral systems as diamond, graphite crystallises in the hexagonal system.

• According to legend, all of the carbon atoms in diamond have strong chemical bonds with the other four carbon atoms, forming a perfect tetrahedron structure throughout the crystal.
