Which of the following products will be obtained in the given (consider minor product also) Beckmann rearrangement?

Which of the following statements is wrong?

Which of the following compounds,upon hydrolysis followed by heating,gives a product that yields a positive iodoform test?

Complete reaction of acetaldehyde with excess formaldehyde,upon heating with conc. $NaOH$ solution,gives $P$ and $Q$. Compound $P$ does not give Tollens' test,whereas $Q$ on acidification gives positive Tollens' test. Treatment of $P$ with excess cyclohexanone in the presence of catalytic amount of $p$-toluenesulfonic acid $(PTSA)$ gives product $R$. Sum of the number of methylene groups $(-CH_2-)$ and oxygen atoms in $R$ is....

Which one of the following gives a yellow precipitate with iodine and $NaOH$ solution?
