CHEMISTRY IN EVERYDAY LIFE QUIZ-3
Dear Readers,The one subject in NEET which is candidates who can easily attain good marks is Chemistry. That's the reason, often, one doesn’t pay notice and choose to compromise it. But if one wants to rank above others, the tip is to be thorough with NEET chemistry concepts. The understanding of reactions and definite basic understanding is what requires major attention in Chemistry but once done it only gets simpler from there. The main focus on the to-do list should be on getting a hang of the NCERT syllabus of NEET chemistry.
Q1. Interferon is:
Solution
Q2.Which detergent can cause maximum pollution?
-
-
-
- Detergents are always pollution free
Solution
(a) Greater the branching, greater is the non-biodegradability of a detergent. A non-biodegradable detergent cause maximum pollution
(a) Greater the branching, greater is the non-biodegradability of a detergent. A non-biodegradable detergent cause maximum pollution

Solution
Q9.What type of a propellant was used in rocket SLV-3 which was fired by India?
Solution
(a) Some rocket fuels are given below: 1. Saturn booster rocket : Kerosene + LiquidO2 for initial stage, liquid O2+Liquid H2 for higher stage. 2. Titan ballistic missile : Hydrazine +N2 O4 3. Space shuttle : Liquid H2+Liquid O2 4. Proton (Russian rocket) : Kerosene + Liquid O2 5. SLV (Space launch : Solid propellant vehicle) and ASLV (Augmented space launch vehicle) 6. PSLV (Polar space : Solid propellant in 1st and 3rd stage and biliquid propellant launch vehicle –an Indian like N2 O4+Unsymmetrical dimethyl hydrazine (UDMH) in the rocket recently launched) second stage and N2 O4+ Monomethyl hydrazine in the fourth stage

Q10. Which of the following groups is not an auxochrome?
- —N(CH3)2
- —H
- —OCH3
-
Solution
A dye molecule is made up of two different parts (i) Chromophore (Greek : chroma = colour, phoros = bearing) and (ii) Auxochromes (Greek : auxo = increase, chroma = colour). The groups which produce colour in a compound, i.e., chromophores are usual unsaturated groups like nitro, nitroso, azo, azoxy, carbonyl and olefinic bonds. Auxochromes are usually acidic / basic functional groups like —OH, —COOH, —SO_3 H, —NH_2,—NHR, —NR_2. A compound containing only a chromophore may be a coloured material but not a dye, e.g., azobenzene is red coloured but not a dye whereas p-aminoazobenzene (aniline yellow) is a dye.
