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

Which of the following compounds does not give an Aldol condensation reaction?

The reaction of $CH_3CH_2CHO$ with $PCl_5$ yields a product. Identify the type of dihalide formed.

In the following compounds,the ones that give positive iodoform test are:
$(I)$ $CH_3CH_2COCH_2CH_3$
$(II)$ $CH_3CH(OH)CH_3$
$(III)$ $1$-indanone
$(IV)$ $CH_3CH_2COCH_3$
$(V)$ $PhCOPh$
$(VI)$ $PhCOCH_3$

Given below are two statements: Statement $I$: The condensation reaction between $CH_{3} - CH = O$ and $H_{2}N - NH - C(=O) - NH_{2}$ under optimum pH will produce $CH_{3} - CH = N - N(H) - C(=O) - NH_{2}$. Statement $II$: The molecule, $Ph - CH(OH)(OCH_{3})$ will generate $Ph - CH = O$ in the presence of dilute acid. In the light of the above statements, choose the correct answer from the options given below:

Reaction of ethyl formate with excess of $CH_3MgI$ followed by hydrolysis gives
