question 11

Multiple Choice

When choosing between two unbiased estimators of the same parameter, the preferred estimator is:

• A) the one that is most unbiased.
• B) the one with the smaller variance.
• C) the one that has an expected value equal to the parameter.

Definitions:

AntiAromatic

Compounds that possess cyclic, conjugated systems with 4n π electrons, which destabilize the molecule and make it less stable than expected.

NonAromatic

A compound that does not fulfill the criteria for aromaticity, lacking a continuous ring of p-orbitals.

[10]Annulene

A cyclic compound with a ten carbon ring structure, which may or may not exhibit aromatic characteristics depending on its substitution pattern and ring geometry.

All-Cis Form

A molecular configuration where all substituents are positioned on the same side of a double bond or in a cyclic structure.
