Question

Draw electronic dot structure CH3-CH3​

Answer 1

Answer:

answer is correct

Explanation:

think you are meaning ‘CH3–’ by ‘CH3'.

The CH3- Lewis structure has a total of 8 valence electrons. This includes the electron represented by the negative charge in CH3-.

If you calculate the formal charges for CH3-, you'll find that the Carbon has a -1 charge and the Hydrogen atoms each have a formal charge of zero. This gives the entire structure a -1 charge.

On the periodic table, Carbon has 4 valence electrons. Hydrogen has 1, but we have three Hydrogens. Then we have this negative up here so we need to add an additional valence electron for a total of 4 plus 3 plus 1: 8 valence electrons. We'll put the Carbon in the centre. Hydrogen always goes on the outside.

The carbanion has three bonding pairs and one lone pair.

Therefore, VSEPR theory predicts a tetrahedral electron geometry and a trigonal pyramidal electron geometry.
