Which of the following molecules is/are polar? i.HF ii.BH₃ iii.CBr₂F₂ iv.PF₃ A)ii only B)i and ii C)ii and iv D)i, iii, and iv E)i, ii, iii, and iv

Question

Quizplus · Accepted Answer

i. HF (hydrogen fluoride) is polar due to the significant electronegativity difference between hydrogen and fluorine, creating a dipole moment.ii. The molecule represented seems to be a formatting error and cannot be evaluated.iii. CBrClF (assuming the intended molecule is CBrClF due to the pattern of symbols) is polar because it has a tetrahedral shape with different atoms around the central carbon, leading to a net dipole moment.iv. PF3 (phosphorus trifluoride) is polar because it has a trigonal pyramidal shape due to the lone pair on phosphorus, causing a net dipole moment.
