Ans: The answer is fumaryl chloride.
The reaction that is given in the question is Friedel craft acylation. This reaction is used to introduce an acyl group that is RCO- onto an aromatic ring with the help of acid halide that is in the presence of Lewis acid catalyst. The equation for Friedel-Crafts acylation is:
Ar-H + RCOX + Lewis Acid → Ar-COR + HX
The reactions which cannot be applied to prepare an alkene by elimination, are
Choose the correct answer from the options given below:
A quantity \( X \) is given by: \[ X = \frac{\epsilon_0 L \Delta V}{\Delta t} \] where:
- \( \epsilon_0 \) is the permittivity of free space,
- \( L \) is the length,
- \( \Delta V \) is the potential difference,
- \( \Delta t \) is the time interval.
The dimension of \( X \) is the same as that of:
