( a ) Draw the skeletal structure of following compounds: [ Lukiskan struktur rangka bagi sebatian - sebatian berikut: ] ( i ) Isohexane. [

(a) Draw the skeletal structure of following compounds:
[Lukiskan struktur rangka bagi sebatian-sebatian berikut:]
(i) Isohexane.
[Isoheksana.]
(1 Mark/Markah)
(ii)1-bromo-2-chloro-3-methylcyclohexane.
[1-bromo-2-kloro-3-metilsikloheksana.]
(1 Mark/Markah)
(iii)5-(1-methylethyl)nonane.
[5-(I-metiletil)nonana.]
(1 Mark/Markah)
(iv)2,2,4-trimethylpentane.
[2,2,4-trimetilpentana.]
(1 Mark/Markah)
(b) Alkane is a hydrocarbon that has only single bonds. The boiling point of an alkane depends on the strength of the attractive force between the individual molecules. [Alkana merupakan hidrokarbon yang mempunyai hanya ikatan tunggal. Takat didih alkana bergantung kepada kekuatan daya tarikan antara molekul individu.]
(i) Explain about the attractive force that held together alkane molecules.
[Terangkan tentang daya tarikan yang memegang molekul alkana.]
(3 Marks/Markah)
(ii) Hexane and 2,2-dimethylbutane has similar molecular weight but different boiling point. Predict which one has lower boiling point and justify your answer.
[Heksana dan 2,2-dimetilbutana mempunyai berat molekul yang sama tetapi takat didih yang berbeza. Jangkakan yang manakah mempunyai takat didih yang lebih rendah dan justifikasikan jawapan anda.]
(3 Marks/Markah)
(c) The different spatial arrangements of the atoms that result from rotation about a single bond are called conformational isomers. Chemists commonly use Newman projections to represent the three-dimensional structures that result from rotation about a sigma bond.
[Perbezaan susunan ruang atom-atom hasil daripada putaran pada ikatan tunggal dikenali sebagai isomerisma konformasi. Kebiasaannya ahli kimia menggunakan unjuran Newman untuk mewakili struktur tiga dimensi yang terhasil daripada putaran pada ikatan sigma.]
