The enolic form of acetone contains:

Q. Number of sigma bonds, pi bonds and lone pair on Xe atom of XeOF(1) 4, 1, 1(2) 4, 2, 1(3) 5,1,1(4) 6,2,0

Q. CH3)2CO + H2N–OH Product. The number of sigma and pi bonds and lone pair of electrons on the product formed sigma pi lone pairs (1) 10 1 3 (2) 11 1 3 (3) 9 1 2 (4) 11 1 2 Options: (1) (2) (3) (4)

Q. The outer orbitals of C in ethene molecules can be considered to be hybridized to give three equivalent sp2 orbitals. The total number of sigma and pi bonds in ethene molecule is 1) 1 sigma and 2 pi bonds 2) 3 sigma and 2 pi bonds 3) 4 sigma and 1 pi bonds 4) 5 sigma and 1 pi bonds

Q. 71. How many sigma bond π bond lone pair are present in P4O10 and P4O6

Q. Bond angle in water molecules is 104.5^° instead of109 28' mainly because of (1) Lone pair-bond pair repulsion (2) Bond pair-lone pair repulsion (3) Lone pair-lone pair replusion (4) Bond pair-bond pair repulsion
