C6h6ncl on the basis of the molecular formula, 1h nmr data, and ir data provided, propose a consistent structure.

h`nmr data: δ 300 (s, 2h), 6.57 (d, 2h), 7.05 (d, 2h)
ir data: 3400 (broad), 3250 (broad), 1590, 820 cm^(-1).

draw your proposed structure below.

Please refer to the attachment below.

Explanation:

Please refer to the attachment below for explanation.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
