does anyone have a good method to identify those.
i am having serious problems with those
please help me out!

arent E1/E2 always with strong base and heat....FOr E2, YES! you need strong base with heat like KOH/heat, or
K+ t-butok - / heat. But for E1 you wont see strong bases, and heat is not needed. you will see stuff like ethyl alcohol.
Sn1: protic solvents to neutralize the carbocation formed, good leaving group, nucleophile strength doesnt matter for Sn1.... prefers tertiary, secondary, primary, methyl [Correct]
Sn2: polar aprotic solvents so it doesnt react with nucleophile in solution, good leaving group, strong nucleophile because the rate is determined by [nucleophile] and [reactant]... prefers methyl, primary, secondary, tertiary...

Nice answer
thank all for replies,
but strong base and heat are required to E1 to occur?
is this true?
If it is secondary...
These are the toughest to figure out. If nucleophile is weak and is a weak base, it will be both SN1 and E1. Strong base, weaker nucleophile goes E2 (such as a hindered base). Strong nucleophile, weak base goes SN2(such as Iodide). Strong nucleophile and strong base will get a mess of elimination and substitution products.
