What two conditions necessary for molecules to be polar? Her's my answer pls check.

First, at least one covalent bond in the molecule has to be a polar covalent bond. For a bond to be polar, there must be a difference in the electronegativities of the two atoms that are bonded together. The second condition is that the molecule cannot be perfectly symmetrical.

Perfect answer. Go to the head of the class.

Well, that's an "electric" answer! You're pretty much on the "positive" track. Molecules indeed need two conditions to be polar. Absolutely electronegativity is a "bonding" factor – the greater the difference, the more polar the bond becomes. And as for symmetry, well, life isn't always fair. A perfectly symmetrical molecule might "juggle" its charges symmetrically too, making it nonpolar. So, asymmetry is the "key" to being polar. Keep up the "charge" of learning!

Your answer is correct.

The two conditions necessary for molecules to be polar are:

1. At least one covalent bond in the molecule has to be a polar covalent bond. This means that there must be a difference in electronegativities between the two atoms that are bonded together. Electronegativity is a measure of an atom's ability to attract electrons. If the electronegativities of the two atoms in a bond are different, then the electrons will be unequally shared, creating a partial positive charge on the less electronegative atom and a partial negative charge on the more electronegative atom.

2. The molecule cannot be perfectly symmetrical. If a molecule is perfectly symmetrical, then the charges within the molecule will cancel each other out, resulting in a nonpolar molecule. Only when the molecule is asymmetrical, with an uneven distribution of charge, will it be polar.

Overall, both the presence of a polar covalent bond and the asymmetry of the molecule are necessary conditions for a molecule to be polar.

Your answer is correct! Two conditions necessary for molecules to be polar are:

1. Presence of polar covalent bond: At least one covalent bond in the molecule must be polar. A polar covalent bond occurs when there is a difference in electronegativity between the atoms involved in the bond. Electronegativity is a measure of an atom's ability to attract shared electrons towards itself. The greater the difference in electronegativity, the more polar the bond.

2. Asymmetry of the molecule: The molecule must not be perfectly symmetrical in order to be polar. If the molecule is symmetric, the bond polarities cancel each other out, resulting in a nonpolar molecule. To determine symmetry, one can use molecular symmetry rules, such as considering the arrangement of atoms and lone pairs around the central atom. If there is an asymmetry in the molecule, the bond polarities do not cancel out, making the molecule polar overall.

Great job in explaining the conditions necessary for molecules to be polar!
