Question
A molecule of ammonia (NH3) has(a) only single bonds(b) only double bonds(c) only triple bonds(d) two double bonds and one single bond
Solution
The correct answer is (a) only single bonds.
Here's why:
-
Ammonia (NH3) is a molecule made up of one nitrogen atom (N) and three hydrogen atoms (H).
-
In ammonia, the nitrogen atom forms three single covalent bonds with three hydrogen atoms.
-
A single covalent bond is a bond that involves sharing of one pair of electrons between two atoms.
-
Therefore, ammonia does not have any double bonds (which involve sharing of two pairs of electrons) or triple bonds (which involve sharing of three pairs of electrons).
-
So, the correct answer is (a) only single bonds.
