Question
Which, if any, of the reactions shown below leads to the indicated product under the specified conditions? All of the above would work. None of the above would work. Which nitration treatment with HNO_3/H_2SO_4) reaction(s) illustrated show(s) the correct product for the indicated starting material? Anisole(CH_3OC_6H_15) rightarrow 4-nitromethoxybenzene Chlorobenzene rightarrow para-chloronitrobenzene para-Chlorotoluene rightarrow 2 nitro-4-chlroeotoluene All the above reactions show the correct products None of the above is correct. Place the four compounds shown in decreasing order of acidity (i.e., most acidic first). 1 > 2 > 3 > 4 2 > 3 > 4 > 1 3 > 4 > 1 > 2 4 > 1 > 2 > 3 None of the above is the correct order, Which, if any, of the reactions shown gives the indicated product? All of the above give the indicated product None of the above give the product. What is (are) the product(s) of the reaction shown?Explanation / Answer
6.) The answer is (c).
In case of (a) the final product should be cyclopenatanone derivative but here it is a cyclohexanone derivative.
In case of (b) the final product is phenylacetic acid but here it is phenylacetamide.
7.) The answer is d.
In case of (a) ,(b) methoxy, chloro is a ortho, para directing group. So they will direct the incoming group to the para position since the ortho position is sterically hindered. In case of (c) chloro is weakly ortho, para directing group whereas methyl is a strong ortho para directing group.
8) The answer is (e)
The correct answer is 4>3>2>1
The conjugate base, benzoate anion is stabilised more in 4-nitrobenzoic acid, than in 4-bromobenzoic acid, than in benzoic acid, than in 4-methylbenzoic acid. Since the electron withdrawing nature of substitents is of the order nitro>bromo>hydrogen>methyl.
