Question

Consider the thioformaldehyde molecule.

What is the central atom? Enter its chemical symbol.How many lone pairs are around the central atom?
What is the ideal angle between the carbon-hydrogen bonds?
Compared to the ideal angle, you would expect the actual angle between the carbon-hydrogen bonds to be ____

Answer 1

In thioformaldehyde molecule,

Central atom - C

lone pairs on central atom - zero

Ideal bond angle between the carbon -hydrogen bonds -
`120^(o)`

Compared to the ideal angle, you would expect the actual angle between the carbon-hydrogen bonds to be
`120^(o)`.

Step-by-step explanation:

The structure of thioformaldehyde is as follows. (in attachment).

From the structure,

Central atom - C

There is no lone pairs are present on the carbon atom, Hence,lone pairs on central atom - zero

The geometry of thioformaldehyde is Trigonal planar.

Hence, the ideal bond angle is
`120^(o)`.

Ideal bond angle between the carbon -hydrogen bonds -
`120^(o)`

All bonds in the thioformaldehyde is similar. Therefore,actual angle between the carbon-hydrogen to be
`120^(o)`.
