Sex and marital specialists can be just as helpful when it comes to loss of libido, so get over your resistance to asking for directions, and call one. Check with your doctor or urologistto rule out any medical conditions that may be playing a part.
Carbon is least electronegative so its attraction for electrons will be least so it will have a greater positive charge and alternatively fluorine will have a greater negative charge, so F-C bond is most polar. In F-N ,nitrogen will have lesser positive charge than carbon and fluorine will have a lesser negative charge as compared to in F-C and so on.
The presence of appreciable electronegativity favors ionic bond formation. The simplest way to determine which of the ionic bonds are strongest is to examine the electronegativities of the anion (the negative portion of a compound) and its cation (the positive portion of the compound). Linus Pauling developed a list of numbers that quantified the property of electronegativity.
