Answer 1

Answer:

i m sorry

dunno the answer

Answer 2

The species which is isostructural with PH3 is XeO3.

• The geometry and shape of a species are decided by the formula
• $electron \: pair \: = \frac{v + mc + a}{2}$
• Here, v is the valence shell electron, m is several monovalent species, c is the cationic charge and a is an anionic charge.
• PH3 has 4 electron pairs, 3 bond pairs and 1 lone pair.
• $electron \: pair \: = \frac{5+ 3}{2} = 4$
• So, PH3 has a pyramidal shape.
• Similarly, XeO3 has electron pair 4 because $electron \: pair \: = \frac{8}{2} = 4$, 3 bond pairs and 1 lone pair.
• PH3 and XeO3 both have a pyramidal shape
