Answer 1

Answer 4):- a) The geometry of H-C$\equiv$C-H is linear around both the 'C' atoms.

b) The molecular geometry of N_{2​​​​​​​}H​​​​​​​₄ is trigonal pyramidal around both 'N' atoms.

c) The molecular geometry of CH₃NH₂ is tetrahedral around 'C' atom and trigonal pyramidal around 'N' atom.

d) The molecular geometry of CH₃COOH is tetrahedral around first 'C' atom and trigonal planar around second 'C' atom.
