Question

POLARITY We've already talked about electronegativity and how to predict whether a bond is polar or nonpolar. For example: Pure covalent bond = sharing of electrons between two identical atoms (with the same electronegativity and no difference in charge) i.e. O2 Polar covalent bond = sharing of electrons between two or more different atoms with a difference in electronegativity. i.e. HCI Just as a bond can be polar or nonpolar, we can also classify an entire molecule as polar or nonpolar. A molecule is said to be polar if the overall (net) effect of all the dipole moments in each bond do not cancel each other out. To determine polarity of a molecule, we first determine the molecular geometry and then draw an arrow pointing from the positive to negative side of each bond. The overall effect of each dipole is then considered. After you draw the molecular geometry, consider what would happen to the central atom if you tied a rope to each of the outside atoms and pulled. Or, if you're morbid (like the textbook I stole these pictures from) consider what would happen to the man below: He stays He put... moves... meaning the SO3 molecule is nonpolar. meaning the SOCI, molecule is polar.

Answer 1

the ans is given below

Quel Find Polar S non Polar caly is because los or meutralize direction non-polar molecule electronegativity difference dipole direction in by all oppsite Tchahedral CHCl CHCIz has polar nature because C-H bond is non polar and c. ci bond have polarity towards- a atom so due to one ch Bond at have effective dipole. a se - Non Polar Ei Because Both are some alom so dipole generale due to one is cancelled by second so It is nonfolar molecule

Polar Nature Because It have one lone pair (negative) and So-a bond, so polarity be sna bond is different than is negative lone pair so due to this have effective dipale moment. " I moment: HO Polar Nahore at have two lone pair and two oth bond polarity direction is toward o alom because of electronegativity difference. So due to different polarity b/w on and lone pair It have polar nature NO Hon polar Because bond and Planar to no It have resonance blo p o so All No bond are equal equal bond in 0 triangular geometry is non polar due effect dipole I ſ

Polar Due to It have It is having effective polar Bent dipole nature. shape so Bent shape Mon holar Because of eranly eranly distribution a of density 6/0 BF bond in triangle geometry it is non- polar electron planar Si0 - non polar 0=S= has linear one si-o so it is Because SiO generated by by another shope bond mon so is polar. polarity concelled So-si-o] Incar shape PFs - --- Hon Polar Because It gf flaxonial molecule so all bond have ealanly Election density which is cancelled out with each other, So It is non polar nature.

Polar Nature te So to doc Due have this dipole to having a distorted I-F bond so one lone pair at structure have some nebulting is polar molecule e dipole so It Polar Due to having lone pair st have Distorted structure. . S F bond have resulled polarity in & direction so due to this st have not a and it is polar. dipole and
