Explain the validity of Heisenberg’s uncertainty principle only for minor particles not for big matters. The uncertainty in the momentum Δp of a sphere travelling at 2000 cm/s is 1.01×10−6 of its momentum. Compute the uncertainty in position Δx given that the mass of the sphere is 500 g.

(c) If we replace the hydrogen atoms in ammonia with the ethyl moieties (C2H5)3— N),
there is no change in the hybridization of central oxygen atom, yet they have different
bond angles, Why? Which molecule has lower bond angle? Give reasons to support
your answer.
(d) What is the simplest justifications for believing that molecular structure is more often
governed by BP-BP/BP-LP/LP-LP repulsions than by the van der Walls repulsions of
the nonbonding electrons on the substituent atoms?
