Butanol convert into propanol
1st method C3H7CH2OH oxidized into AcidC3H7COOH then NH3and hoffman broamide(Br2+KOH) C3H7NH2 and treted with,HNO2 C3H7OH
2nd butanol undergoes dehydration ,ozonolysis then we get propanal and metanal .propanal with LiAIH4 give propanol

H2Te is more acidic than H2S
Dear victoria as the size of anion increses bond strenth of M-H bond decrese so H eaisly release

HOT ICE
Sodium acetate is also used in consumer heating pads or hand warmers and is also used in “hot ice”. When sodium acetate trihydrate crystals (melting point 58 °C) are heated to around 100 °C, they melt. When this melt cools, it gives a supersaturated solution of sodium acetate in water. This solution is capable of supercooling to room temperature, well below its melting point, without forming crystals. By clicking on a metal disc in the heating pad, a nucleation center is formed which causes the solution to crystallize into solid sodium acetate trihydrate again. The bond-forming process of crystallization is exothermic, hence heat is emitted. The latent heat of fusion is about 264–289 kJ/kg (Source).
Is water is more acidic than ROH
yes water is more acidic than ROH becoz HO- is more stable than RO-
