You have to state more precisely WHERE the second methyl-group and the amine-group is situated before this Q. can be answered.
No, it is NOT either both. Besides 'benzenepropanol' is not an official name.
Yes it is. It's structural isomer is ethanol C2H5OH
1,2-dichloropropane exists as an optical isomer.
I can't remember what you get but it's optically inactive because it's a racemic mixture. Which means that there is a 50:50 ratio of the (+) optical isomer and the (-) optical isomer. It's inactive because the (+) rotates plain polarised light clockwise and the (-) isomer rotates plain polarised light anticlockwise. So they cancel each other out because it's a racemic mix and therefore shows no optical activity.
2-methyl-2-propaneamine (isopropylamine) is neither an optical isomer nor a geometric isomer. Optical isomers arise from chirality (having a non-superimposable mirror image), whereas geometric isomers arise from restricted rotation around a double bond or ring. In the case of isopropylamine, it is a branched molecule without a chiral center or a double bond, so it does not exhibit optical or geometric isomerism.

Optical isomers are those which have one or more asymmetric carbon atoms their optical activity means a tendency to rotate the plane of plane polarized light but some of such molecules have an internal symmetry as meso form of Tartaric acid , this is the optical isomer of Tartaric acid but is optically inactive.

A racemic mixture is one of two optical isomers. By way of analogy, your right hand is the mirror image of the left, there are chemical compounds that this also occurs in. In the body most chemical reactions are mediated by proteins called enzymes. Enzymes are not simple compounds and are very selective in how they bind reactants. That being the case, they only work with one optical isomer and the end products are always of one optical isomer. see http://www.answers.com/optical+isomer
Geometrical isomerism is a space isomerism which is noticed in the organic compounds having double bond and arises because of restricted or hindered rotation of the atoms or groups about double bond. Geometrical isomers differ in their physical and chemical properties. Melting point and stability of the cis isomers are lower than those of the trans isomer. Boiling point, solubility, density, dipole moment, refractive index and heat of combustion are higher for the cis isomer than the trans isomer.

D and L are optical isomer of each other, or non superimposible mirror images. The convention uses Glyceraldhyde as the reference. In a fisher projection the OH of glyceraldehyde is on the right side ( more improtantly in the R configuration)in the D isomer and on the left side ( or the molecule is in the L configuration) in the L isomer. So for all other sugars it looks at the last chiral center for the molecule if the chiral center is R it is a D isomer if the last chiral center is in the S configuration it is an L isomer.

trans isomers
No. CaCl2 is neither ans isomer, nor does it have isomers.
