(a) Ionic Solids do not dissolve in non-polar solvents. (TRUE OR FALSE)
(b) H3AsO4 is a weak acid. (TRUE OR FALSE)
(c) Once a chemical reaction has come to equilibrium, the reaction comes to a complete halt.(TRUE OR FALSE)
Consider the molecules PH, and PMe,. If these molecules were
classified as Lewis bases and were to react with BH,, then:
(a) The adduct formed with PH, would have the strongest B–P
bond.
(b) The adduct formed with PH, would have the longest B-P
bond.
(c) The adduct formed with PH, would have a double bond
between P and B, B=P, because PH, is sterically unhindered.
(d) The adduct formed with PMe, would have the strongest B-P
bond.
(e) The adduct formed with PMe, would have the weakest B-P
bond because PMe, is very sterically hindered.
