Answers
Q . 1 Ans – Tollen’s Reagent is a chemical reagent used to
distinguish between aldehydes and ketone functional groups and its prepare
sodium hydrate Is Added to a solution
Silver nitrate dropwise until a light brown light precipitate is
obtained .
Q .2 . Ans⇒ Adding a base decreases the conc.
of H3O+ ions in the solution . An acid
& base are like chemical oppasites. If a base is added to an Acidic solution.
The solution becomes less acidic & moves toward the middle of the pH scale.
9.3 Ans⇒ In Organic chemistry the most
common funational groups are carbonyl(c=0) alcohol (-OH) Carboxylic acids (co2H)
esters (CO₂R) and amines ( Nh2) .
