Answer:
Higher chain length, higher boiling point
Polar species are soluble in similar polarity water, Non polar species are soluble in similar non polar oil.
Step-by-step explanation:
Chain length refers to the number of carbons. As it increases, boiling points of alkanes increase for these compounds. Reason behind is that longer chain molecules become more entangled along with each other.
Polarity bonds atoms together, by chemical bonding - through sharing seperated electric charge ie electrons. Polar Solvents have large dipole moments, contain bonds between atoms with different electro negativities. Non Polar solvents contain bonds between atoms with similar electro negativities.
- Polar species are soluble in water, as it is from same category. Non Polar species are soluble in oil, as it is from same category. Substances with same polarity are soluble in each other, substances with different polarities are different from each other.
