Fifth group elements form hydrides to type AH_(3) . The hydrides have a lone pair of electrons. The hydries are reducing in nature and the reducing power is related to the stability of A-H bonds. The hydrides are covalent and low boiling. Their boiling points depends on their ability to from hydrogen bond and their molecular size which decide the intermolcular forces in the hydrides . The H-M-H bond angle of V group hydrides decrease from 107^(circ) to 90^(circ) for NH_(3) to SbH_(3) , this is due to:

Why is the H-O-H bond angle in H_(2)O smaller than H-N-H bond angle in NH_(3) ?

Assertion : H-S-H bond angle in H_(2)S is closer to 90^(@) but H-O-H bond angle in H_(2)O is 104.5^(@) Reason: lp-lp repulsion is stronger in H_(2)S than in H_(2)O

Boron forms a numbr of hydrides having the general formuale B_(n)H_(n+4)1 and B_(n)H_(n+6) These hydrides are called boranes. The simpest hydride of boron is diborane, B_(2)H_(6) . Boranes contain special types of bonds known as multicientre bonds. Bornaes have high of combustion. From B_(2)H_(6) . which of the following can b e prepared except:

A particle is thrown with speed u at an angle of projection theta with horizontal as shown. (i) The avergae velocity of particle from O to A is u cos theta (ii) The average velocity of particle from O to H (highest point) is (u)/(2) sqrt(1 + 3 cos^(2) theta) (iii) The average velocity of particle from J to K is u cos theta (iv) The angle between the velocity and the acceleration between O and H is greater than 90^(@) , between H to A is less than 90^(@) and at highest point is 90^(@)

The angle of elevation of the highest point P of a vertical tower at point A on the horizontal ground is 45^(@) . The height of tower is 'h'/ The angle of a elevation of the tower becomes 60^(@) from B on moving a distance 'd' at 30^(@) angle from the horizontal. Prove that: d=h(sqrt(3)-1)
