MDCAT 2026 MCQs

Electrical power can be written P=VI.
It may also be expressed as I²R or V²/R.

A triple bond reduces hydrogen count by four relative to an alkane.
The general formula becomes CnH2n-2.

A capacitor consists of separated conductors.
Its capacitance measures charge stored per unit potential difference.

Functional groups determine much of a molecule's chemistry.
Examples include hydroxyl, carbonyl, and carboxyl groups.

Capacitance is C=Q/V.
Its SI unit is the farad.

Alcohols contain an -OH bonded to a saturated carbon.
Their properties include hydrogen bonding.

Magnetic fields are produced by magnets and moving charges.
Their direction is indicated by field lines.

An aldehyde has a carbonyl carbon bonded to at least one hydrogen.
The group is commonly written -CHO.

Magnetic force is qvB sinθ in magnitude.
It changes direction of motion but does no work on the charge.

A ketone carbonyl carbon is bonded to two carbon groups.
It occurs within the carbon skeleton.

Faraday's law links induced emf to the rate of magnetic-flux change.
Relative motion or changing current can produce induction.

The carboxyl group combines carbonyl and hydroxyl functions.
Carboxylic acids can donate a proton.
