Q1.
butane = alkane (nonpolar, will not be soluble in water)
2-chlorobutane = haloalkane (polar, will be soluble in water)
Haloalkanes ar emuch reactive
addition of AgNO3 + ethanol + heating will cause precipitation, whereas butane will not
Q2
butane vs. 1-butanol
butane --> will have lower BP --> approx -1-2°C , i.e. it is a gas at room T
butanol --> will have OH group which makes it polar, there will be hydrogne bonding as well, boiling point is higher, 117.7 °C
butane -- alkane (nonpolar, will not be soluble in water)
butnaol = (polar, will be soluble in water)
Q3
1-butanol + 2-butanol
1-butanol = Primary alcohol
2-butanol = secondaru alcohols
both are polar + hydrogen bonded, so expect solubility
addition of oxidant such as permangante will:
oxidize primary carbon to COOH, i.e. carboixlic acid ( terminal group
oxidize seocndary carbon to C=O, i.e ketone
Q4.
1-butanol + butanoic acid
1-butanol has almost a neutral pH; whereas butanoic acid has a lwoer pH, i.e. pH = < 7
butanoic acid will react readily with bases, change of pH is also expected
1-butanol will not likely react with mildbases
