How to choose the base compound ? And start counting from that ? IS there is a prioty list ?

i think this should be the answer but everywhere i looked it doesn't have +2

Proply is c3h8 not 6 but in 2nd and 3rd example in main thread, in 3rd it means - propyl mean C3H5 Iso means 1 branch of methyl on 2nd but in 1st and 2nd example it doesn't follow that @exchemist

Is the book self-contradictory or am I tripping. Also what is the order of preference for base substituent ?

@exchemist thanks alot you are my guru

Also why there is +ve charge on II ?

what does having x2 sp hybridized orbital mean ? In C-C triple bond x2 sp hybridized orbitals are formed, but in questions earlier it has taught that 1 sigma bond = s, 2 = sp, 3 = sp2 Uploading Attachment... Uploading Attachment...

Double bond use 2p orbitals per C atom in C-C double bond and also in triple bond how ? @exchemist

@exchemist thanks

@exchemist in 2nd example Propy is c3h8 not H6

this makes me question alkane if CnH2n+2, so with 1 double bond should be (CnH2n+2)-2 removing 2 H (from adjacent C atoms) frees one 1 bond for double bond. If there are 2 double bonds then 2x2 H are lesser so (CnH2n+2)-2x2 For 3 double bonds (CnH2n+2)-2x3 Am i right @exchemist One day i wish i be able to pay you back for all the Knowledge and encouragement.

@exchemist need help understanding nomenclature

Title

'You have already read that the pi (π) bond is a weaker bond due to poor sideways overlapping between the two 2p orbitals." 1 pie bond is actually 2 bonds as it need 2 p orbitals

CnH2n-2d ?

Chloromethyl ? C3H5 what is that ? 1. Supposed to be CH3Cl which should be Chloromethyl Ethyl Propyl

What is acetate ? not methyl carboxylic acid Why is O negatively charged oxygen has 6 electrons and when bond it's got 7 if it losses 2 what is 5 but the middle part has 7 electrons oxygen has 6 electrons and when bond it's got 7 if it losses 2 what is 5 but the middle part has 7 electrons oxygen has 6 in valence free radicals has single electrons in their orbital in the valence shell, making atom unstable, reactive, shifts electron cloud Reaction is from

5-isopropyl Iso means 1 branch of methyl on 2nd Propyl is c2h4 not 6 Sec-butyl is c with 2 other c attache and another fcitonal group attached Also iso thing Propy is c3h8 not 6 Here propyl mean C3H5

@exchemist sorry struggling with thermodynamics

How does this conversion multiplication works ? @exchemist Dhanyavad

5-isopropyl Iso means 1 branch of methyl on 2nd Propyl is c2h4 not 6 Sec-butyl is c with 2 other c attache and another fcitonal group attached Also iso thing Propy is c3h8 not 6 Here propyl mean C3H5 What is tetra What is tert Chloromethyl ? C3H5 what is that ? 1.

@sethoflagos @exchemist thank you In standard gibs energy 25C is used are STP. what does multiplying with 760 and 273 achieve. @sethoflagos sorry sometimes I take time to reply and my English is good, that is Arabic for thank you you wrote not any Indian language 😀

@exchemist thanks alot

Double bond - C2H4 should be longer than C2. And if a more electro negative is added to C2H4 single bond or C2H6 double bond, length should reduce further.
