Chapter 21, Problem 51P
Interpretation Introduction
Interpretation:
We have to name the dangerous ingredient in kohl which is a very widely used product.
Concept Introduction:
Kohl or commonly known as kajal is a popular eye care product. It has been claimed to improve vision, keep the eyes cool and clean, and strengthen the eyes without any side effects. It has also been used for the prevention and treatment of eye diseases such as cataract, blepharitis, conjunctivitis etc. As a result of such claims, it is widely used by people across societies around the world. But recent research has shown that some ingredients if Kohl is harmful to the body and can be proved very dangerous for prolonged use.

6. Consider the following exothermic reaction below.
2Cu2+(aq) +41 (aq)2Cul(s) + 12(aq)
a. If Cul is added, there will be a shift left/shift right/no shift (circle one).
b. If Cu2+ is added, there will be a shift left/shift right/no shift (circle one).
c. If a solution of AgNO3 is added, there will be a shift left/shift right/no shift (circle one).
d. If the solvent hexane (C6H14) is added, there will be a shift left/shift right/no shift (circle
one). Hint: one of the reaction species is more soluble in hexane than in water.

- 1. For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
