Step by step
Solved in 2 steps
- Write down the Miller index in the grid direction that may be placed on the grid plane (112) among the <110> aromatic groups.fill in the blanks. If there are unshared pairs of electrons on the atoms directly attached to the aromatic ring, they are the groups that provide electrons to the ring with the effect of ……………… and are ………………… directive towards electrophiles. Groups that are double bonded to a more electronegative atom than the atoms directly attached to the ring are ……… steers that withdraw electrons from the ring with the effect of … Groups whose electronegativity is higher than the sp2 carbon of the ring directly attached to the ring will withdraw electrons from the ring as ............. and ……… they are routers. Halogens, on the other hand, withdraw electrons from the ring as ………......... due to their high electronegativity and are ……….. directing.Select the michael donar species of the following structure?

- 1 i. What is Resonance Theory? Sate five conclusions that can be drawn from the theory. ii. State the two main experiments that were used to establish the extra stability of the benzene molecule. iii. What are the factors that confer Aromaticity to an organic molecule? iv. State the effects of substituents on a benzene derivative towards further aromatic substitution. V. Based on the above suggest the various types of substituents that can be attached to Benzene.The instructions were to define if the molecule was aromatic or antiaromatic. If the element (such as N or O) has a double bond directly on it, then its lone pair doesn't count in the conjugation system; if there's a single bond, then its lone pair is counted. I counted the electrons on the lone pairs, and since the total was 6 e-, I labeled it as aromatic. was this correct?Is this molecule aromatic? Why doesn't the pi bond in the benzene ring on the left side not count torward aromaticity?
- Which of these images are not aromatic?As the extent of electron delocalization into the ring increases, the geometry at nitrogen flattens. p-Nitroaniline, for example, is planar. Write a resonance contributor for p-nitroaniline that shows how the nitro group increases electron delocalization.Thoroughly describe what is meant when a compound is considered aromatic. In your answer, provide examples and be sure to discuss how Huckel's Rule applies, and what it means to be anti-aromatic versus non-aromatic. When providing specific examples to demonstrate the requirements that you list, describe the delocalized pi electrons and sp2 hybridization. Lastly, why is benzene so special compared to alkenes like cyclohexene....both are 6-carbon atom cycles so are they chemically similar or not really similar at all?
- Is the molecule aromatic, antiaromatic, or non-aromatic? Why?Predict the electronic configurations of (a) the benzeneanion, (b) the benzene cation. Estimate the π-bond energy in each case.Please write down the resulting products. How can I know which of the two substituents already present is more strongly conducting in the case of double-substituted benzene? Is generally ortho preferred to para? In the example of OH and NH2 both otho,para conducting. So are there three possible products?
