The specific worksheet usually asks students to complete equations, draw mechanisms, and identify products based on different reagents and conditions.
If you have a specific question from the Chemsheets "Reactions of Halogenoalkanes 1" task, I can help you: for a specific molecule.
The primary reaction type covered in Chemsheets 1 is nucleophilic substitution. In these reactions, a nucleophile replaces the halogen atom. 1. Reaction with Aqueous Sodium Hydroxide (OH⁻) NaOH (aq) or KOH (aq). Conditions: Warm/Heat under reflux. Nucleophile: The hydroxide ion (:OH⁻). Product: Alcohol.

Use this guide to check your worksheet answers, then try redrawing every mechanism from memory. That is the path to an A*.
Even though the C-F bond is the most polar, it is also the strongest. It requires the most energy to break. Weakest bond, reacts the fastest. The specific worksheet usually asks students to complete
CH₃CH₂Br + NaOH → CH₃CH₂OH + NaBr Conditions: Warm aqueous solution, reflux. Explanation: This is an SN2 reaction. The OH⁻ nucleophile attacks the δ+ carbon attached to bromine, kicking out the bromide ion (a leaving group). The product is ethanol.

Excellent. Chemsheets has a strong reputation for exam-board alignment. The answers correctly distinguish between SN1 vs SN2 mechanisms (including curly arrow notation, partial charges, and transition states where required) and accurately predict product mixtures (e.g., elimination vs substitution based on conditions).
Strongest bond, reacts the slowest (often not at all under standard conditions).
