Naming a carbon compound can be done by the following method –
(i) Identify the number of carbon atoms in the compound. A compound having three carbon atoms would have the name propane.
(ii) In case a functional group is present, it is indicated in the name of the compound with either a prefix or a suffix.
(iii) If the name of the functional group is to be given as a suffix, the name of

Best Coaching Class Notes by admin (#1) 450 days ago (http://www.youtube.com)
Metals are the elements that conduct heat and electricity and are malleable and ductile. Metals are also lustrous (Shiny) , hard, strong heavy and sonorous (.i.e. they make ringing sound when struck ). Some of the examples of metals are Iron, Aluminium, Gold, Platinum, Copper, Mercury, Zinc, Tin, Lead, etc.
