Question

A molecule with the formula ab3 could have one of four different shapes. give the shape and the hybridization of the central a atom for each.

Answer 1

A molecule with the formula AB3 could have one of four different shapes: trigonal planar, trigonal pyramidal, T-shaped, or linear. The hybridization of the central A atom depends on the number of sigma bonds and lone pairs on the atom.

Step-by-step explanation:

A molecule with the formula AB3 could have one of four different shapes depending on the number of lone pairs on the central atom: trigonal planar, trigonal pyramidal, T-shaped, or linear.

The hybridization of the central A atom in each shape can be determined using the number of sigma bonds and lone pairs on the atom. For example, in a trigonal planar shape, the central atom has sp2 hybridization because it forms 3 sigma bonds. In a trigonal pyramidal shape, the central atom has sp3 hybridization because it forms 3 sigma bonds and has 1 lone pair.

Example molecules for each shape are BCl3 for trigonal planar, NH3 for trigonal pyramidal, ClF3 for T-shaped, and BrF3 for linear.

Answer 2

Trigonal planar and SP^2 hybridization of the central atom of molecule with ab^3 formula.

This molecule is made up of 3 equally spaced sp^2 hybrid orbital arranged at 120 degree angles. The shape of the orbital is planar triangular since there is an atom at the end of each orbital.
