particle theory All matter consists of many very small particles which are constantly moving or in a continual state of motion. Use of the general term ‘particle’ means the precise nature of the particle does not have to be specified. The particles may be ions‚ atoms or molecules. The particle theory of matter states: ● all matter is made up of tiny particles ● these particles are in a continual state of motion ● matter is held together by very strong electric forces ● the empty spaces between the

therefore is less reactive than haloalkane towards nucleophilic substitution reaction. 2. Haloalkanes react with KCN to form alkyl cyanide as main product while AgCN form isocyonide. Ans. KCN is‚ predominantly ionic compound and provide cyanide ion : C N in solution. The attack mainly takes place through lone pair of electron on carbon atom due to high electron density and not through nitrogen atom since C-C bond is more stable than C-N bond. AgCN: is mainly a covalent compound therefore‚ nitrogen

Amanda Jornd Experiment 7- Synthesis and Reactivity of tert-Butyl Chloride Via an SN1 Reaction Introduction/Background: Alkyl halides are compounds in which a halogen atom replaces a hydrogen atom of an alkane. Alkyl halides are classified as primary‚ secondary or tertiary depending on the number of alkyl substituents directly attached to the carbon attached to the halogen atom. The purpose of this lab was to properly prepare t-butyl chloride from t-butyl-alcohol in a concentrated hydrochloric

1.5.1 Comparison of Three Isomers of Butanol Introduction: An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). If the OH is bonded to only one other carbon‚ it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons‚ it is a secondary alcohol (eg. 2-butanol);
