What chiefly determines the polarity of a bond?

Using electronegative. If the difference is between 0 and .4, the bond is nonpolar,If the difference is between .4 and about 1.9, the bond is polar, and if the difference is over 1.9 it is typically ionic.

what's the

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
