What is the difference between a constitutional, confirgurational, and a conformational isomer?

Explain What are conformational isomerism?

a. Which of the following statements concerning a pair of geometrical isomers are correct?(1) They have different boiling points and melting points.(2) They have the same relative molecular mass.(3) Their atoms are joined in the same order.A. (1) and (2) onlyB. (1) and (3) onlyC. (2) and (3) onlyD. (1), (2) and (3)b. Which of the following statements concerning enantiomers is INCORRECT?A. If a pair of enantiomers is present in the same amount, the mixture is optically inactive.B. A pair of enantiomers has the same melting point.C. There is at least one plane of symmetry in the molecules of enantiomers.D. A pair of enantiomers has the same molecular formula.

Match the pair of compounds with the type of isomerism. Choices:a. positional isomerb. cis, trans configurationc. diastereomerd. enantiomere. functional isomerf. skeletal isomerg. E.Z configuration

4. Optical isomerism occurs when a molecule's mirror image is superimposable. b. both cis and trans isomers exist in equal concentrations. two or more structural isomers of a molecule exist. а. с. d. at least one carbon atom in a molecule is bonded to four different atoms or groups. e. both enantiomers are present in a racemic mixture.

I belive that the two are diastereomers beause theres seem to be a cis-trans isometry?
