Assertion : The solubility of a gas in a liquid increases with increase of pressure.
Reason : The solubility of a gas in a liquid is directly proportional to the pressure of the gas.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
If phthalic acid is treated with NH3 and then it is first heated weakly then strongly, the final product formed is
Which is correct example of condensation polymer?
Nylon, Buna-S
Teflon, Buna-N
Nylon 6,6, Dacron
Neoprene, Buna-S
C.
Nylon 6,6, Dacron
Nylon 6, 6 and dacron are the examples of condensation polymers. Condensation polymers are formed by condensation of two or more bifunctional monomers with the elimination of simple molecules like H2O, NH3, alcohol, etc. Dacron is formed from ethylene glycol and terephthalic acid with the removal of H-O. Nylon 6, 6 is formed from hexamethylenediamine and adipic acid with the removal of HO.
But-1-ene
The product in the above reaction is
CH3CH2CH2CH2OH
CH3
CH2CH(OH)CH3
CH2=CH2CH(OH)-CH3
CH3-CH=C(OH)-CH3
An aromatic compound C7H6Cl2 (A), gives AgCl on boiling with alcoholic AgNO2 solution and yields C,HOCI on treatment with sodium hydroxide. (A) on oxidation gives monochlorobenzoic acid. The compound (A) is:
Assertion: HC= C- is more stable than H2C CH-
Reason : HC C- has more s-character than HC= CH-
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
