1. "If there is a chiral carbon then it is optically active." - This statement is generally correct. A chiral carbon atom, also known as an asymmetric carbon atom, is a carbon atom that is attached to four different types of atoms or groups of atoms. This leads to molecules that cannot be superimposed on their mirror images, making them optically active.

2. "If there is no plane of symmetry then the compound will be optically active." - This statement is also generally correct. A molecule that lacks a plane of symmetry, also known as a chiral molecule, is optically active because it can exist in two non-superimposable forms, known as enantiomers.

3. "In Fischer projection, the vertical line represents the group towards the observer." - This statement is incorrect. In Fischer projections, horizontal lines represent bonds that project out from the plane of the paper (towards the observer), while vertical lines represent bonds that extend behind the plane of the paper (away from the observer).

4. "2-Chlorobutane shows optical isomerism." - This statement is correct. 2-Chlorobutane has a chiral carbon (the second carbon atom), and thus it exists as two enantiomers, making it optically active.
