Ethyl bromide forms when 1 molecule of ethene (Upper C Subscript 2 Upper H Subscript 4) and 1 molecule of hydrobromide (Upper H Upper B r) react completely.

Question

If ethyl bromide is the only product of the reaction, how many atoms are in 1 ethyl bromide molecule?

Answer options with 4 options
A.
2

B.
3

C.
4

D.
8

Answer 1

To determine the number of atoms in a molecule of ethyl bromide (C2H5Br), we can break it down by counting the number of atoms of each element present in the molecule:

• There are 2 carbon (C) atoms.
• There are 5 hydrogen (H) atoms.
• There is 1 bromine (Br) atom.

Now, we can add these together:

• Total number of atoms = 2 (C) + 5 (H) + 1 (Br) = 8 atoms.

Therefore, the answer is D. 8.
