Production of Halogenoarenes Halogenoarenes?are arenes which are bonded to?halogen?atoms They can be prepared from?substitution reactions?of arenes with chlorine or bromine in the presence of an an...
Arenes: Directing Effects of Substituents Arenes readily undergo?electrophilic substitution?of one of their hydrogen atoms with another species Substituents?that are already present on the arenes c...
Arenes: Location of Halogenation Arenes will undergo substitution reactions?with halogens to form aryl halides This reaction is also called a?halogenation?reaction Depending on the reaction conditi...
Arenes: Electrophilic Substitution The?electrophilic substitution?reaction in arenes consists of?three steps: Generation of an?electrophile Electrophilic attack Regenerating?aromaticity Mechanism o...
Reactions of Arenes Arenes are very stable compounds due to the?delocalisation of π electrons?in the ring This is because the negative charge is spread out over the molecule instead of being confin...
隨著科技的發(fā)展，互聯(lián)網(wǎng)時代下對科技人員的需求日益增多。而計算機相關(guān)專業(yè)一直是留學生的熱門選擇之一，在澳洲留學生群體之間更是如此。很多熱衷于計算機科學Master of computer science 的留學生們，也將澳洲大...
Chirality & Drug Production Most of the drugs that are used to treat diseases contain?one or more?chiral centres These drugs can therefore exist as?enantiomers?which differ from each other in t...
