Octahedral crystalline variety of sulphur contain 'X'S - S bonds in which covalency of sulphur is y. It contains 'Z' lone pair of electrons. Then (z - x - y) is
(A ) 9
(B) 12
(C) 4
(D) 6

The distance of the point (x,y,z) from xy-plne is (A) x (B) |y| (C) z (D) |z|

Allyl cyanide [CH_(2)CHCH_(2)CN] having "x" sigma bonds, "y" pi bonds and "z" lone pair electrons then "x-y-z" is

Sulphur is more stable in the form of rhombic sulphur which contains S_(8) rings. This on heating converts into vapour that consists of S_(2) fragments.The correct statements about these S_(8) and S_(2) molecules. (A) S-S bond length is more in S_(8) than in S_(2) . (B) S_(8) ring is diamagnetic whereas S_(2) is paramagnetic. C) in S_(8) and S_(2) mlecules there are two lone pairs of electrons on each sulphur atom

A molecule XY_(2) contains two sigma bonds two pi bond and one lone pair of electrons in the valence shell of X . The arrangement of lone pair as well as bond pairs is

In \(ICl_{3}\) the total number of lone pairs is x. In \(ClO_{2}^{-}\) lone pairs on Cl is y. The oxidation state of lodine in IBr is z. then (x+z)/y is

In \(ICl_{3}\),hybridization of I is \(sp^{x}d^{y}\) and number of lone pairs on "|" are "z. x+y+z is

Grapes placed in three beakers X ,Y and Z containing different type of solutions are shown in figures. If beaker X contains water, Y and Z contain

The sum of all the coefficients of the terms in the expansion of (x+y+z+w)^(6) which contain x but not y , is

A plane which passes through the point (3,2,0) nd the line (x-4)/1=(y-7)/5=(z-4)/4 is (A) x-y+z=1 (B) x+y+z=5 (C) x+2y-z=1 (D) 2x-y+z=5
