(a)
Interpretation:
The Lewis structure of given molecule is to be drawn.
Concept introduction:
Lewis structure is a representation of a molecule which shows shared and unshared pair of electrons. It is helpful to determine the shape of a molecule.
(a)
Answer to Problem 35A
Explanation of Solution
Nitrogen has five valence electrons. Each electron is shared by each bromine atom and two electrons are left unshared. There will be 3 lone pair each on the Br atom because Br atoms have total of 7 valence electrons and only 1 electron is involved in bonding.
(b)
Interpretation:
The Lewis structure of given molecule is to be drawn.

Lewis structure is a representation of a molecule which shows shared and unshared pair of electrons. It is helpful to determine the shape of a molecule.
(b)
Answer to Problem 35A
Explanation of Solution
Fluorine has seven valence electrons and hydrogen has one valence electron. So, both share one electron with each other to complete doublet of hydrogen and octet of fluorine. Also, there will be 3 lone pair of electrons on F atom.
(c)
Interpretation:
The Lewis structure of given molecule is to be drawn.

Lewis structure is a representation of a molecule which shows shared and unshared pair of electrons. It is helpful to determine the shape of a molecule.
(c)
Answer to Problem 35A
Explanation of Solution
Carbon has four valence electrons. Each electron is shared by one bromine atom and no electrons are left unshared. There will be 3 lone pair each on the Br atom because Br atoms have total of 7 valence electrons and only 1 electron is involved in bonding.
(d)
Interpretation:
The Lewis structure of given molecule is to be drawn.

(d)
Answer to Problem 35A
Explanation of Solution
Carbon has four valence electrons. One electron of carbon is shared with hydrogen to complete its doublet and carbon shares three electrons with other carbon to complete octet and no electrons are left unshared.
