what is this, why are you worried, brush up with simple things, you will come out genius, learn with me, small drops of water make an ocean, you will be an expert in this

4-methylbenzaldehyde
The proton NMR has three peaks; a singlet at 
2.2 (3H), and a singlet at 10 (1H) and two doublets centered around 7.6. The doublets centered at 7.6 are in the aromatic region; the fact that two doublets are observed (2H each) suggests a 1,4-disubstituted aromatic compound.
The peak at 2.2 is in the region for a methyl group adjacent a mildly electronegative group. The singlet at 10 is in the region observed for aldehydic protons. The presence of two doublets in the aromatic region is highly characteristic of 1,4-disubstitution.
τι είναι αυτό, γιατί είσαι ανήσυχος, βούρτσα με απλά πράγματα, θα βγει ιδιοφυΐα, να μάθουν μαζί μου, μικρές σταγόνες του νερού κάνει έναν ωκεανό, θα είστε ένας εμπειρογνώμονας σε αυτό
methyl acetate (methyl ethanoate)
The proton NMR has two singlets of equal area. The fact that the molecule has 6 hydrogens means that there must be two non-identical CH3 groups in the molecule and that they are non-adjacent. The peak at 1.95 is in the area generally observed for methyl groups adjacent to carbonyls; the peak at 3.85 is in the region for methyl groups adjacent to electronegative atoms, i.e., oxygen.
আপনি চিন্তিত কেন এই সহজ জিনিস নিয়ে ব্রাশ,, কি, আপনি, প্রতিভা বাইরে আসতে আমার সাথে শিখতে হবে, জলের ছোট ঝরিয়া একটি মহাসাগর না, আপনি এই একজন বিশেষজ্ঞ হতে হবে
The proton NMR has a quartet and a triplet, indicating a CH2 adjacent to a CH3. The peak at 2.5 is in the area generally observed for methyl groups adjacent to mildly electronegative groups; the peak at 1.2 is in the region for simple methyl groups adjacent to carbons (CH3CH2). The molecule contains oxygen, but the peak at 2.5 is not shifted enough for this to represent an -O- linkage, so it must represent a carbonyl.
acetaldehyde (ethanal)
The proton NMR has two peaks; at high resolution, fine coupling is evident between them (J 
1 Hz) with the peak at 9.7 being a quartet and the peak at 2.1 being a doublet, indicating a CH coupled to a CH3. The peak at 9.7 is in the area generally observed for aldehydic protons; the peak at 2.1 is in the region for a methyl group adjacent a carbonyl. The molecule contains oxygen, but the peak at 2.1 is not shifted enough for this to represent an -O- linkage, so it must represent a carbonyl. The very small coupling constant suggests that the proton and the CH3 group are not immediately adjacent, but that this represents an example of cross-space coupling.

Name: ethyl acetate (ethyl ethanoate)
The proton NMR has three peaks; a quartet at 4.1 (2H), a triplet at 1.2 (3H) and a singlet at 1.97 (3H). The quartet and triplet suggest a CH2 coupled to a CH3 in an ethyl group. The peak at 4.1 is in the area generally observed for CH groups adjacent to electronegative groups, i.e., oxygen. The peak at 2 is in the region for a methyl group adjacent a carbonyl.

methyl vinyl ether (methyl ethenyl ether)
3.6 (3H) is consistent with an isolated CH3 group adjacent to an electronegative center, such as oxygen. The sets of highly split doublets centered at 6.5, 4.2 and 4.0 (there is overlap of these at 4.1) span the region where alkene hydrogens are observed. The complex splitting pattern observed resembles an ABC pattern for a terminal alkene.

Name: 1,2-dimethoxyethane
4-isopropyl-1-methoxybenzene (4-(1-methylethyl)-1-methoxybenzene)
3.6 (3H), two sets of doublets centered around 6.9 (4H), a septet at 2.7 (1H) and a doublet at 1.6. The singlet at 3.6 is consistent with an isolated CH3adjacent to an electronegative center, such as an oxygen. The septet and doublet strongly suggest an isopropyl group 
CH(CH3) 2 in which the carbon is bonded to something mildly electronegative and the two doublets centered at 6.9 strongly suggest a 1,4-disubstituted aromatic compound.
3-bromomethyltoluene (3-bromomethyl-1-methylbenzene)
4.3 (2H), a messy singlet around 7.1 (4H), and a singlet at 2.3 (3H). The singlet at 2.3 is consistent with an isolated CH3 adjacent to a mildly electronegative center. The singlet at 4.3 is consistent with a CH2 group adjacent to two mildly electronegative centers (X-CH2-Y), and the singlet at 7.1 is consistent with a disubstituted aromatic compound. The substitution pattern is not what is normally seen in 1,4-disubstitution (two doublets), suggesting 1,2 or 1,3-disubstitution.
