Iodomethane (CH3I) is a commonly used reagent in organic chemistry. When used properly, this reagent allows chemists to introduce methyl groups in many different, useful applications. The chemical does pose a risk as a carcinogen, possibly owing to iodomethane’s ability to react with portions of the DNA strand (if they were to come in contact). Consider the following hypothetical initial rates data:
Which of the following could be a possible mechanism to explain the initial rate data? Mechanism I DNA + CH3I → DNA–CH3+ + I2
Mechanism II CH3I → CH3+ + I2 Slow
DNA + CH3+ → DNA–CH3+ Fast
