Jan 12, 2018 17:50 IST

    In this article, students who are preparing for UPSEE/UPTU entrance examination 2018 will get complete revision notes of chapter Hydrocarbons including preparation, chemical properties and physical properties.

    UPSEE/UPTU 2018: Hydrocarbons
    UPSEE/UPTU 2018: Hydrocarbons

    Organic Chemistry is one of the most important parts of the Chemistry in the syllabus of UPSEE/UPTU entrance examination 2018. Because of the tough competition in engineering entrance examinations students can’t skip any topic of any subject.

    Organic Chemistry is the study of structure, preparation, physical properties and chemical properties of carbon containing compound. The chapter ‘Hydrocarbons’ is the base of the Organic Chemistry. It is very important to understand this chapter to understand the other topics of Organic Chemistry like Haloalkanes and Haloarenes, Alcohols, Phenols and Ethers etc.

    In this article, students will get study notes and previous years’ solved questions related to chapter Hydrocarbons which will help in your preparation for UPSEE/UPTU entrance examination.

    Students can revise the following topics here:

    1. Preparation of alkanes from unsaturated hydrocarbons, alkyl halides and carboxylic acid

    2. Physical properties of alkanes

    3. Chemical properties of alkanes

    4. Preparation of alkenes from alkynes, alkyl halides, vicinal dihalides and alcohol

    5. Physical properties of alkenes

    6. Chemical properties of alkenes

    7. Preparation of alkynes from calcium carbides and vicinal dihalides

    8. Physical properties of alkynes

    9. Chemical properties of alkynes

    Question 3:

    Provide the systematic name of the compound shown:

    UPSEE Hydrocarbons Question 3

    (A) 4 – butyl – 1 – ethyl – 2 – methylcycloheptane

    (B) 4 – butyl – 2 – ethyl – 1 – methylcycloheptane

    (C) 1 – butyl – 4 – ethyl – 3 – methylcycloheptane

    (D) 2 – butyl – 4 – ethyl – 1 – methylcycloheptane

    Solution 3:

    UPSEE Hydrocarbons Solution 3

    Naming according to closest set of locant rule is 4 – butyl – 1 – ethyl – 2 – methylcycloheptane.

    Hence, the correct option is (A).
