I also said (c) in the very first reply but that was to explain the given answer as done by any teachers in chemistry.. :P

c is one step . but d is a multistepone so after amny processes you get the product.

so , yield is less as in any organic reaction yield can very very rarely reach 100%

i think (c)

but beware LiAlH4 is too dangerous :P

Abhishek Priyam ·

But options were given and c was out

If options were not then can you ever say a numerical answer...

I also did once a parabola question and i said √2 and it was right aur sab dekhte rah gaye :P
