I hope you don't mind shivbaba:, that I merged your diverse questions into one thread.  However, like billnotgatez: said, we like to see a little more effort from people asking questions.  Lets at least see your attempts.

b)Potassium Bromide
c)Calcium Fluoride

My assumption :K+ is bigger cation ,which favours ionic bond formation .and fluoride is smaller anion which again favours ionic bond formation. but those ions are in two different ionic compounds.based on what factor we should take into account to decide feasibility of compound formation..

a)single bond
b)double bond
c)triple bond

My assumption :i read sigma bond is  just like a cylindrical electron cloud around the inter nuclear axis.but when pi bond is formed  it is dispersed above and below the sigma bond .because of presence of  pi bond the symmetry of double bond will disappear or not ??how to find out the symmetry of double and triple bond?

d)overlapping of orbitals takes place but no bond formation

My assumption: in valence bond theory i read that" two orbitals
 with two unpaired electrons  should interact with opposite spin".so i expect only orbital overlapping and no bond formation. is it correct?
