Some specific compounds that do contain asymmetric carbons are: Pseudoephedrine: this compound contains two asymmetric carbon atoms. One of them is the carbon bonded to the -OH group, and the other is the carbon bonded to the nitrogen atom.

Carbon and chlorine ond is polar due to electronegativity difference between C-Cl and all molecules containing carbon and chlorine bond will be polar except carbontetrachloride because it has dipole moment of zero due to its geometry.

This means that if the shape of the molecule given to you is a bent or trigonal pyramid, it is a polar molecule. Remember that asymmetry applies even if the outer atoms are the same. The arrangement of the atoms matters more. Now, let's dissect the symmetric molecules.

In α amino acids (molecule at left), both the carboxylic acid group (red) and the amino group (blue) are bonded to the same carbon center, termed the α carbon ( ) because it is one atom away from the carboxylate group. In β amino acids, the amino group is bonded to the β carbon (

The cis isomer is a diastereomer of the trans isomers. ... Since the cis isomer has two centers of chirality (asymmetric carbons) and is optically inactive, it is a meso-compound. The corresponding trans isomers also exist as rapidly interconverting chiral conformations.

['Non polar molecules are symmetric with no unshared electrons.', 'Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.']

1-Butene consists of a chain of four carbons, having a double bond between carbons 1 and 2. Because carbon 1 has two of the same substituent (in this case, H), 1-butene does not exhibit geometric isomerism, unlike its structural isomer, 2-butene (see below).

C2Br2 : If we look at this structure then there is symmetry in it. Due to this symmetry dipole moments of 4 C-Br bond is cancelled and resultant dipole moment of the molecule is 0. Therefore molecule is non polar.

In double bond there are two hydrogen atoms attached to each carbon . As carbon has atomic no. 6 and other most shell has4 electrons . It needs more 4 elections to be stable .

A organic molecule is a name for a set of any bonded atoms that contains carbon, a organic compound is a name for a set of bonded atoms that contains carbon but must contain a different atom, such as hydrogen. Diamond or graphite are molecules that contains only carbon so they are not compounds.

In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds. Because of this symmetric geometry, CCl4 is non-polar.

A molecule will be polar if it has a net dipole. Both the C-H and the C-N bonds are polar. Nitrogen is more electronegative than carbon which is more electronegative than hydrogen.

When molecules have an even charge distribution and no dipole moment, then they are nonpolar molecules. CO2 is a linear molecule, so our dipoles are symmetrical; the dipoles are equal in magnitude but point in opposite directions. Generally, when dipole distribution is symmetrical, there is no dipole moment.

restricted rotation (often involving a carbon-carbon double bond for introductory purposes); two different groups on the left-hand end of the bond and two different groups on the right-hand end. It doesn't matter whether the left-hand groups are the same as the right-hand ones or not.

A molecule of carbon tetrachloride contains one carbon and four chlorine atoms.

A molecule that can be cut into two identical halves is said to be symmetrical. The oxygen atom is also symmetrical with no permanent charge on the molecule. A polar molecule such as HCl is not symmetrical. It therefore has two opposite charged ends.

Chloroform, CHCl3 is a polar molecule. Molecules which are asymmetrical are usually polar, as is the case for CHCl3. The vector sum of the individual bond dipoles is nonzero, giving it a net dipole moment, which is to say that it is polar.
