Answer to Question #153315 in Physical Chemistry for Giren

Question

Draw the shape of a molecule of a named compound (or species) which has the bond angle indicated: A. 109.50 B. 1200 C.1050

ii) Explain the differences in shape between the molecules A and B above.

Answer 1

The above given is answer for shape of molecule and compound name with bond angle.

CH4 methane is sp3 hybridized that's why it has 109.5 ° bond angle and tetrahedral shape.

Ethylene has sp2 hybridized that's why it has 120° bond angle and trigonal planar shape.

And deu to strong lone pair lone pair repulsion in water it has 105° bond angle. Here O is sp3 hybridized and H2O is V shaped.
