In comparision to Clemmensen reduction, both $\ce{Na-Hg}$ and $\ce{Al-Hg}$ cannot be used as direct substitutes for $\ce{Zn-Hg}$. Reaction with $\ce{Na-Hg}$ amalgam: $\ce{Na-Hg}$ amalgam is also a good reducing agent and is capable of reducing ketones/aldehydes to alcohols1. However, Do not use conc. $\ce{HCl}$ with $\ce{Na-Hg}$ amalgam, as there would be a ...


The correct question (taken from the 2016 JEE Paper is): Lithium Aluminium Hydride reduces epoxides1, hence (A) would not give the required product. LAH also reduces ethers to primary alcohols, which is an easier way of eliminating the option (A). $\ce{BH3}$ in THF can reduce the acid, as explained in this question, hence the requisite product would not be ...


The inversion takes place at a single carbon inbetween, so 2^1 = 2. Knowing that the mechanism takes place at the carbonyl carbon, the inversion takes place at one point only. It will not form several stereoisomers, only two at the reaction centre.


The only case I know of where activated carbon causes reduction at room temperature would be filtration of ozone, $\ce{O3}$. Even fluorine will not oxidize plain carbon: Carbon is stable in a fluorine atmosphere up to about $\pu{400 ^\circ C}$ . Oh, well perhaps dioxygen difluoride, $\ce{FOOF}$, could also oxidize carbon (or could be reduced by carbon, ...
