Answer 1

ANSW

	Alkane	Alkene	Alkyne	Alcohol	Alkyl halyde
Example of structural formula	CH3-CH2-CH3	H2C=CH2	HC≡CH	R-CH2-OH	R-CH2-X (X= Cl, Br, I)
Solubility in water	Not soluble. Hydrocarbons are insoluble in water			Soluble only if the carbon chain has less than 5 carbons	Not soluble. Alkyl halydes are not soluble in water
Solubility in NaOH	Not soluble. There is not acidic protons that can react with diluted NaOH to form an ionic compound which is soluble
Solubility in HCl	Not soluble. There is not basic groups that can react with diluted HCl to form an ionic compound which is soluble
Ceric nitrate test	Not reacts			Alcohols with up to 10 C form a pink or red colored complex	Not reacts
Silver nitrate test	Not reacts			Not reacts	Formation of a precipitate: AgCl (white), AgBr (cream) or AgI (yellow)
2,4-DNPH test	Not reacts. This test is for ketones or aldehydes
Tollen's test	Not reacts. this test is for aldehydes
Bromination test	Not reacts	Color of bromine solution disappears		Not reacts
Bromothymol blue test	Not reacts. These type of compounds does not have acid or basic properties to produces a color change of bromothymol blue reagent
Phenolphthalein test	Not reacts. These type of compounds does not have acid or basic properties to produces a color change of phenolphthalein reagent
