1H NMR OF SIMPLE MOLECULES.. Brush up

New Drug Approvals

ما هو هذا، لماذا أنت قلق، فرشاة مع الأشياء البسيطة، وسوف يخرج عبقري، وتعلم معي، قطرات صغيرة من الماء جعلالمحيطات، وسوف يكون خبيرا في هذا

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

あなたが心配している理由は、これは簡単なことでブラッシュアップ、、何か、あなたは、天才が出てくる私と一緒に学ぶことが、水の小さな滴が海を作るには、この専門家になる

4-methylbenzaldehyde

NMR SpectrumThe 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…
