Question

write the molecular formula and structural formula of benzene . Name the type of covalent bond formed between the hydrogen atoms in a molecule of hydrogen ​

Answer 1

Answer:

Question 2

Define

(a) a chemical bond

(b) an electrovalent bond

(c) a covalent bond

Solution 2

(a) A chemical bond may be defined as the force of attraction between any two atoms, in a molecule, to maintain stability.

(b) The chemical bond formed between two atoms by transfer of one or more electrons from the atom of a metallic electropositive element to an atom of a non-metallic electronegative element is called as electrovalent bond.

(c) The chemical bond formed due to mutual sharing of electrons between the given pairs of atoms of non-metallic elements is called as a covalent bond.

Answer 2

Answer:

molecular formula and structural of benzene C6H6

covalent bonds between hydrogen and oxygen atoms in water are polar covalent bonds. The shared electrons spend more time near the oxygen nucleus, giving it a small negative charge, than they spend near the hydrogen nuclei, giving these molecules a small positive charge.
