Answer : The correct option is, (c) pyramidal
Explanation :
As we are given that a molecule in which the central atom forms three single bonds and has one lone pair that means the central metal atom has 3 bond pairs and 1 lone pair of electrons.
There are total 4 electron pairs. So, the hybridization will be and the electronic geometry of the molecule will be tetrahedral.
But as there are three atoms or bonds around the central atom and the fourth position occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be pyramidal.
Hence, correct option is, (c) pyramidal
Nitrogen combine with hydrogen to produce ammonia at a
ratio:
Assuming that the reaction has indeed proceeded to completion- with all nitrogen used up as the question has indicated. of hydrogen gas would have been consumed while
of ammonia would have been produced. The final mixture would therefore contain

Apply the ideal gas law to find the total pressure inside the container and the respective partial pressure of hydrogen and ammonia:
