Q

WHAT IS A CHAIN ISOMER?

A

THE CARBON BACKBONE IS ARRANGED IN DIFFERENT WAYS MEANING THE MOLECULAR FORMULA IS THE SAME BUT THE STRUCTURE AND NAME IS DIFFERENT

Q

WHAT IS A GEOMETRIC ISOMER?

A

ATOMS JOINED BY A SINGLE BOND CAN ROTATE FREELY AROUND THE SINGLE BOND, THEREFORE THEY ARE NOT CONSIDERED ISOMERS. HOWEVER, CIS-TRANS ISOMERS CAN OCCUR WHEN THERE IS A DOUBEL BOND

Q

IDENTIFY THE FORCES OF ATTRACTION PRESENT IN ALKANES…

A

NON-POLAR MEANS THE ONLY FORCES OF ATTRACTION BETWEEN MOLECULES ARE WEAK DISPERSION FORCES

Q

DESCRIBE THE EFFECT OF THE LENGTH OF THE CARBON CHAN ON THE BOILING POINT…

A

LONGER CHAIN = OVERALL FORCES ARE STRONGER (TEMPORARY DIPOLES) = HIGH BOILING POINT

Q

DESCRIBE THE EFFECT OF MOLECULAR SHAPE ON BOILING POINT…

A

STRAIGHT-CHAIN ALKANES FIT TOGETHER MORE CLOSELY THAN BRANCHED AND THEREFORE HAVE HIGHER BOILING POINTS

Q

WATER MOLECULES ARE POLAR. ARE ALKANES SOLUBLE IN WATER?

A

NO BECAUSE POLAR + POLAR IS SOLUBLE AND ALL THE ALKANA,ENE,YNES ARE NON-POLAR
