100% sure

خلينا نشوفها من وجهة نظر كيميائية
شوف معايا الصورة هذه

أول صورة على اليسار Unbranched والبقية Branched

أتمنى يكون وضحلك السبب

جواب سؤال 24 E
انا خشيت الانترنت و بحثت عن carbon skeleton و لقيته ممكن يكون بي او دي يعني الاجابة e ان شاء الله
وازا تبغوا تتأكدوا خشوا و ابحثوا :)
و شكرياااا
