Solution Steps

Step 1: Conversion of 1-Propanol to Propene

To convert 1-propanol to propene, we need to perform a dehydration reaction.

  • Reagent and Conditions: Concentrated sulfuric acid (H₂SO₄) and heat.
  • Reaction: \[ \text{CH}_3\text{CH}_2\text{CH}_2\text{OH} \xrightarrow{\text{H}_2\text{SO}_4, \text{heat}} \text{CH}_3\text{CH}=\text{CH}_2 + \text{H}_2\text{O} \]
Step 2: Conversion of Propene to 1,2-Dibromopropane

To convert propene to 1,2-dibromopropane, we need to perform a bromination reaction.

  • Reagent and Conditions: Bromine (Br₂) in an inert solvent like CCl₄.
  • Reaction: \[ \text{CH}_3\text{CH}=\text{CH}_2 + \text{Br}_2 \rightarrow \text{CH}_3\text{CH}(\text{Br})\text{CH}_2\text{Br} \]
Step 3: Conversion of Propene to 2-Bromopropane

To convert propene to 2-bromopropane, we need to perform a hydrohalogenation reaction.

  • Reagent and Conditions: Hydrogen bromide (HBr).
  • Reaction: \[ \text{CH}_3\text{CH}=\text{CH}_2 + \text{HBr} \rightarrow \text{CH}_3\text{CH}(\text{Br})\text{CH}_3 \]

Final Answer

  1. Conversion of 1-Propanol to Propene: Use concentrated sulfuric acid (H₂SO₄) and heat.
  2. Conversion of Propene to 1,2-Dibromopropane: Use bromine (Br₂) in an inert solvent like CCl₄.
  3. Conversion of Propene to 2-Bromopropane: Use hydrogen bromide (HBr).

My 6 kg cat wants to push his box of kitty chow off the table so it will spill a snack for his afternoon "tea". The box has a mass of 1 kg (that's 2.2 lb or 9.8 N of gravitational downward force) and the coefficient of friction with the table top for both kitty paws and box is 0.25 . About how much force does he have to push with to get the box to begin to slide? Pick the closest answer to what you calculate using your understanding of static frictional forces. (A) 15 N (B) 25 N (C) 2.5 N (D) He will slide before the box does (E) 2.2 lb (F) 9.8 N Continue Last saved 4:59:46 PM
