Which of the following is not true in case of reaction with heated copper at 300oC?
Which of the following is a Lewis acid?
"Lewis Acid is something that accepts a pair of electrons."
"A Lewis Base is something that donates a pair of electrons."
So Cl- would be a Lewis base.
NH3 is a Lewis Base.
BF3 is NOT a Lewis Base because it has an empty p orbital, this is a Lewis Acid.
C2H5OH is ethanol and that is a Lewis Base because the Oxygen has two lone pairs of electrons that it can donate.
Which does not contain conjugate system?
In dienes, when the double bonds connected to each other by a single bond, this arrangement is known as conjugated.
Sum of number of ions in aqueous solution of CrCl3.5NH3 and CrCl3 . 4NH3.

if ‘x’ is total number of benzene ring in compound(C) and ‘y’ is the total number of degree of unsaturation in compound (D) then the value of (x + y) is
Identify total number of compound (s) which are unstable at room temperature ?
27 gm of Al react with excess of oxygen to give 4.95 gm of Al2O3, calculate % yield of reaction.
Acidic oxide = CO2, SiO2
x = 2
Neutral oxide = CO
y = 1
2 + 1 = 3
