Answer:
The molecular shape and ideal bond angle of the
is trigonalbipyramidal and
respectively.
Explanation:
The structure of
is as follows.(in attachment)
From the structure,
Phosphor atom has one lone pair and three hydrogens are bonded by six electrons.
Therefore, total electrons invovled in the formation
is eight.
Hence, four electron groups which indicate the tetrahedral shape. But one pair is lone pair i.e, present on the phosphor atom.
Therefore, ideal geometry of the
molecule is <u>Trigonalbipyramidal.</u>
The ideal angle of trigonalbipyrmidal is
.
All three bonds of P-H has
.
Therefore, ideal bond angle is <u>
.</u>
By Gayle-Lussac's law, the pressure and temperature of a fixed volume and amount of gas is directly proportional.
Thus,
P/T = constant
So if the temperature is increased four times, the pressure is also increased four times.
