What are the Silicones? Give one example one cyclic Silicone?

Silicones are organosilicon polymeric compounds containing repeated R₂SiO units and (-Si-O-Si-) linkage.The name is given silicone because their empirical formula is analogous to that of ketones (R₂CO). Silicones may have the cyclic structure also having 3, 4, 5 and 6 nos. of silicon atoms within the ring. Alcohol analogue of silicon is known as silanol.

Why bond angle of hydrides of group 15, decreases down the group?

Hydride: NH₃ > PH₃ > AsH₃ >SbH₃

H-M-H angle: 107 > 92 > 90 > 91 (Degree)

This is due to the decrease in electronegativity of the central atom of hydride. As the electronegativity decrease the electrons which were more close to central atom at lower hydrides tends to more far from it and bp-bp repulsion decreases.
