Match the molecular shapes to the correct lewis structures. (options provided in the image below)

Answer :

(a)

In this Lewis dot structure, there are 3 bond pair and 0 lone pair on the central atom. The total number of electron pair is 3. So, the hybridization of the molecule will be, and the geometry will be, trigonal planar.

(b)

In this Lewis dot structure, there are 4 bond pair and 0 lone pair on the central atom. The total number of electron pair is 4. So, the hybridization of the molecule will be, and the geometry will be, tetrahedral.

(c)

In this Lewis dot structure, there are 3 bond pair and 1 lone pair on the central atom. The total number of electron pair is 4. So, the hybridization of the molecule will be, but the the fourth position will be occupied by one lone pair. Hence, the geometry will be, trigonal pyramidal not tetrahedral.

(d)

In this Lewis dot structure, there are 2 bond pair and 1 lone pair on the central atom. The total number of electron pair is 3. So, the hybridization of the molecule will be, but the the third position will be occupied by one lone pair. Hence, the geometry will be, bent not linear.

The image is also shown below.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
