помогите пожалуйста) составьте формулу 2-метилбутанол-1 и покажите химические свойства этого соединения и составьте изомерные кислоты для 2,3-диметилпропановой кислоты изомеры назовите.
Предмет:
ХимияАвтор:
seniorgkywCH3-CH2-CH-CH2OH (2-метилбутанол-1)
I
CH3
Химические свойства:
1. Так как это соединение спирт, для него характерна реакция горения:
2CH3-CH2-CH-CH2OH + 15О2 → 10СО2 + 12Н2О I CH3
Точно я не помню какие ещё реакции ему присущи, но покажу, что знаю.
2.
2CH3-CH2-CH-CH2OH +2Na → 2CH3-CH2-CH-CH2ONa + H2
I I
CH3 CH3
3. Окисление:
CH3-CH2-CH-CH2OH + CuO → CH3-CH2-CH-COH +Cu +H2O
I I
CH3 CH3
4. Качественная реакция на одноатомный спирт - это реакция с гидроксидом меди Cu(OH)2 , в результате которой осадок растворяется и раствор приобретает тёмно синий цвет.
К сожалению, это всё, что я помню. Одноатомным спиртам присущи реакции - этерификации(образование сложных эфиров), взаимодействуют с соляной кислотой к примеру.
(2,3-диметилпропановая кислота)( и кстати хочу сказать, что такого не бывает чтобы 3 метил...может ошибку какую допустил(а)..)ну на всякий случай вот..
СН2-СН-СOOH это соединение будет называться 2 метилбутановая кислота.
I I
CH3 CH3
Изомеры :
1. СН3 -СН2-СН2-СН2-СOOH (пентановая или валериановая кислота)
2. СН3-СН-СН2-СOOH (3-метилбутановая кислота)
I
CH3
3. СН3-СН2-СН-СOOH (2-метилбутановая кислота)
I
CH3
4. CH3
I
СН3-С-СOOH (2,2 - диметилпропановая кислота)
I
CH3
вот и вроде всё.

Перевести на русский!!!не по переводчику!!!срочно!!!
I got the letter and I couldn't believe my eyes when I saw "D" at the end. Could it really be from David? I wanted it to be from him so much! I decided to meet him. There was only one problem. Our counsellor Jenny doesn't let anybody go out of the cabin after lights out (поcлe ОТБОЯ). What I was going to do was very wrong ... and Jenny was so sweet — she didn't expect me to let her down and deceive her in this way. If I got caught outside the cabin at night, she'd be in deep trouble with the Crunch. On the other hand, David expected me to come. I couldn't let him down, could I? That night I put on my best outfit and went to bed early. Everybody thought I was asleep, but I wasn't. I watched all my bunkmates go to their beds, I heard them talk in sleepy voices and finally everything got quiet. I still had time, so I decided to wait a bit more just to make sure everybody was really asleep. Then I saw Belle get out of her bed. She was fully dressed as well! Where was she going? Belle looked round and quietly walked out of the cabin door. I thought it was time for me to go too, so I followed her after a few minutes. I didn't want Belle to see me, so I watched her leave until she was out of sight. Then I ran straight to the lake. I sat under a huge tree and waited for David. Suddenly I heard somebody. My heart fell when I saw Daniel, the guy from Australia. A lot of girls like him, but I think he is too tough. Dima told me that Daniel once made him swim across the lake, and my brother is not a very good swimmer. At first I didn't want him to see me, so I tried to hide myself behind the tree, but Daniel noticed me right away and came up 10 me. "Hi," he said. To be honest, he looked really surprised. He probably didn't expect me to come when he wrote his stupid letter. "What are you doing here after lights out? Your counsellor wouldn't like you to be here, you know?" he went on. "Besides, it might be dangerous because this area is full of wild animals. I'll walk you back to your cabin." Before I had the time to think of a good answer, Daniel took my hand and made me follow him. We hadn't walked a few steps when I saw David. He was walking in our direction, but then he stopped half-way and turned around. He was obviously looking for Belle, and I certainly wasn't going to help him. I was heartbroken and needed some time alone. A few minutes later we bumped into Charlie who also looked a bit nervous. The lake shore was a surprisingly busy place after dark.
