Which of the following has a steric number of 4?

Water (H 2 O) – Water has two hydrogen atoms bonded to oxygen and also 2 lone pairs, so its steric number is 4. Ammonia (NH 3) – Ammonia also has a steric number of 4 because it has 3 hydrogen atoms bonded to nitrogen and 1 lone electron pair. Ethylene (C 2 H 4) – Ethylene has 3 bonded atoms and no lone pairs.

What has a steric number of 4 in H2O?

Water (H2O) – Water has two hydrogen atoms bonded to oxygen and also 2 lone pairs, so its SN is 4. Ammonia (NH3) – Ammonia also has a steric number of 4 because it has 3 hydrogen atoms bonded to nitrogen and 1 lone electron pair.

What is the steric number of NH3 4?

Ammonia (NH 3) – Ammonia also has a steric number of 4 because it has 3 hydrogen atoms bonded to nitrogen and 1 lone electron pair. Ethylene (C 2 H 4) – Ethylene has 3 bonded atoms and no lone pairs.
