Compound A, C9H12, undergoes nitration to give 3 products. The 1H NMR spectrum of A shows a complex three-proton multiplet at 6.92-6.99 δ and a nine-proton singlet at 2.34 δ. What is the structure of A? You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. In cases where there is more than one answer, just draw one.

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
