Question

Draw the Lewis structure of CH₃Br.

Answer 1

The Lewis structure of CH₃Br is: H | C - Br | H | H.

Step-by-step explanation:

The Lewis structure of CH₃Br can be drawn by following these steps:

1. Count the total number of valence electrons: Carbon (C) has 4 valence electrons and Hydrogen (H) has 1 valence electron. Bromine (Br) has 7 valence electrons. So, the total is 4 + 3(1) + 7 = 14 valence electrons.
2. Place the atoms in the structure: Carbon is the central atom. Hydrogen atoms will be attached to it, and Bromine will be attached to one of the Hydrogen atoms.
3. Distribute the remaining electrons: Using single bonds, connect Carbon to the Hydrogen atoms and to the Bromine atom. Each bond contains 2 electrons. Distribute the remaining electrons as lone pairs on the atoms.
4. Check the octet rule: Make sure all atoms (except Hydrogen) have 8 electrons or have achieved their corresponding duet rule. If any atom lacks electrons, form double or triple bonds as necessary.
