## The product of a reaction series involving 1,3-dithiane, 1-chloro-3-iodopropane and butyllithium

I encountered this question while solving an objective paper....

## Mechanism of three-membered lactone hydrolysis in base

I was reading up on the participation of neighboring functional groups and in the reaction below, I was wondering why hydroxide attacks the C–O bond instead of the carbonyl group...

## What makes C=O more stable that C(OH)₂

When there are $2$ hydroxy groups on same carbon, they tend to undergo dehydration ( of course with exceptions like chloral where $ce H$ bonding prevails). Why does this happen?...

## Confusing stability order of free radical structures

I have a question regarding the solution that has been given. Question:In the given compound, what would be the order of ease with which hydrogen atom can be abstracted from...

## Salt analysis of Ag salts

So I was doing analysis of silver salts and I found $ce{AgBr}$ is curry white partially soluble in ammonia, $ce{AgI}$ is yellowish and insoluble but silver phosphate is...

## Reason for no change in electrode potential in reference electrodes

Reference electrodes such as the saturated calomel electrode and silver chloride electrode have a constant potential because the $ce{Cl-}$ concentration (or, to be more precise, the activity) is constant....

## Why does an mercury ore exist as HgS?

Cinnabar($ce{HgS}$) is one of the most common ores of mercury. Why does it not exist at $ce{HgO}$ or some other such compound? Is there any reason for...

## What is the hybridisation in HCN molecule?

According to VSEPR theory hybridisation of the central atom should be sp. However, my teacher says that there exists a near-100% s-character in the carbon orbital that bonds with hydrogen...

## Crystal Field Theory

When I learned about crystal field theory I had fallen on a paradox. When K4[Fe(CN)6] is formed then three d orbitals are occupied by electrons of Fe2+ pairly and the...
